5 Bulletin Control Circuit and Load Protection General Information Technical Information: The Benefits of Limiting Let-Through Energy Energy Limiting s Versus Conventional Breakers The Bulletin -SP line features the unique ability to achieve short circuit interruptions far more effectively than conventional circuit breakers. In conventional circuit breakers, the short circuit interruption time required is approximately one or two half cycles of an AC sine wave. When the contacts are open, the resulting arc continues to burn until the current level passes through zero. The arc may re-ignite because of the insufficient width of the contact gap. The current that flows until the arc is extinguished produces a heating effect proportional to the It value (let-through-energy) of the fault current. These devices are designed to substantially reduce the amount of let-through-current and the resulting let-through-energy that can damage protected components. They have the ability to interrupt short circuit current within the first half cycle of the fault. Limiting let-through-energy will protect against the harmful effects of over-current and is focused primarily on avoiding the following: Excessive heat Mechanical damage Both of these factors are proportional to the square of the current. Thermal energy is proportional to the square of the RMS value and magnetic forces are proportional to the square of the peak value. The most effective way to provide protection is to subtantially limit letthrough-energy.this provides the following advantages: Far less damage at the location of the short circuit. Fast electric separation of a faulty unit from the system, especially power supplies connected in parallel that are switched off when the voltage of the power bus drops below a certain level. Far less wear on the miniature circuit breaker itself. This means more safe interruptions. Better protection of all components in the short circuit path. Far wider range of selective action when used with an upstream protective device. (No nuisance shut downs from feeder line interruptions causing a blackout in all connected branches.)

7 Continuous Current Rating Bul. -MC circuit breakers are rated in RMS amperes at a C ( F) ambient temperature per UL (CSA. No..). This temperature is generally used as the average temperature within an industrial enclosure. If a circuit breaker is applied in a temperature that exceeds the C ( F) ambient, then the circuit breaker should be derated. Contact your local Rockwell Automation sales office or Allen-Bradley distributor for derating information. The characteristic trip curves are shown on pages - -. The trip bands shown for each breaker represent current tripping limits for a circuit breaker and are within the limits established by UL. For a specific current at C ( F), a circuit breaker will open ("clear the circuit") automatically at some total time that will be within the "Minimum" and "Maximum" time shown as the "Minimum" and "Maximum" curves. For example, page - shows that a one pole, A, -MC trips in not less than s and not more than s on a A current. Because the UL standard defines this time spread, users should not specify exact tripping time. The lower current portion of the curves (upper left) depict the time to trip due to thermal action and reflect overload protection of the wire and connect load. The higher current portion of the curves (lower right) depicts the trip due to magnetic action of the circuit breaker and reflects protection due to short circuit level currents. Standard current ratings are,,,,,,,,,,,,,,, and A. Application Considerations The selection of a specific ampere rating for a specific application is dependent on the type of load and duty cycle and is governed by the National Electric Code (Canadian Electric Code) and UL/CSA. In general the codes require that overcurrent protection is at the current supply and at points where wire sizes are reduced. In addition the codes state that conductors be protected according to their current carrying capacity. There are specific situations that require application consideration, such as motor circuit, and guidelines for the selection for transformer protection. Bulletin -MC circuit breakders are "non-% rated" as defined by UL Part... As such the circuit breaker's rating should be loaded to no more than %, if used with continuous loads. Bulletin -MC Product Description Branch Circuits: Bulletin -MC circuit breakers may be used to protect branch circuits. A branch circuit is the wiring portion of a system extending beyond the final overcurrent device protecting the circuit. Guidelines established in NEC, CEC, UL, and CSA should be used to determine the specific device. For example: ) Motor Branch Circuit Bulletin -MC circuit breakers are not horsepower rated because they are able to safely interrupt currents far in excess of the locked rotor value for a selected motor. This ability is recognized in the codes and standards and is also established by the UL and CSA tests described in UL and CSA C. No.. standards. The size of a Bulletin -MC circuit breaker should be determined following the guidelines for an Inverse Time. References: NEC. and UL A. Also see CEC and appropriate Canadian Standards. ) Transformer Protection Bulletin -MC circuit breakers may be used for transformer protection following the guidelines established. References: NEC and UL A. Also see CEC and appropriate Canadian Standards. ) Heater Load, Lighting, and Other Load Protection Bulletin -MC circuit breakers may be used for protection of heater loads, lighting loads, and other loads following the guidelines established. References: NEC Article and UL A. Also see CEC and appropriate Canadian Standards. Coordinated Overcurrent Protection Where an orderly shutdown is required to minimize the hazards to personnel and equipment, a system of coordination based upon the faulted or overloaded circuit is isolated by selective operation of only the overcurrent protective device closest to the overcurrent condition. The user should select devices that meet this requirement. References: NEC.. Also see CEC. Publication A-CAA-EN-P -

Continuous Current Rating Standard current ratings are:.,,.,,,,,,,,,,,,,,,, and A. The Bulletin -A circuit breakers are rated in RMS amperes at a C ( F) ambient temperature per the UL (CSA. No. ) standard. This temperature is generally used as the average temperature within an industrial enclosure. If a circuit breaker is applied in a temperature that exceeds the C ( F) ambient, then the circuit breaker should be derated. For IEC - standard, the products carry an ambient rating of C. Follow standard IEC application considerations for temperature rating in different ambient temperatures. The characteristic trip curves are shown on page -. The trip bands shown for each breaker represent current tripping limits for a circuit breaker and are within the limits established by UL. For a specific current at C ( F), a circuit breaker will open ("clear the circuit") automatically at some total time that will be within the "Minimum" and "Maximum" time shown on the curves. For example, page - shows that a one-pole, A, Bulletin -A circuit breaker trips in not less than s and not more than s on a A current. Because the UL standard defines this time spread, users should not specify exact tripping time. The lower current portion of the curves (upper left) depict the time to trip due to thermal action and reflect overload protection of the wire and connect load. The higher current portion of the curves (lower right) depicts the trip due to magnetic action of the circuit breaker and reflects protection due to short circuit level currents. Application Considerations The following is a discussion of application considerations related to North American applications. When applying product to IEC regional requirements, follow IEC practices and guidelines. The selection of a specific ampere rating for a specific application is dependent on the type of load and duty cycle and is governed by the National Electric Code (Canadian Electric Code) and UL/CSA. In general, the codes require that overcurrent protection is at the current supply and at points where wire sizes are reduced. In addition, the codes state that conductors be protected according to their current carrying capacity. There are specific situations that require application consideration, such as motor circuit, and guidelines for the selection for transformer protection. The Bulletin -A circuit breakers are non percent rated as defined by UL, para... As such, the circuit breaker's rating should be loaded to no more than % if used with continuous loads. Line and load may be reversed. The Bulletin circuit breaker may be bottom fed. Branch Circuits: Bulletin -A circuit breakers may be used to protect branch circuits. A branch circuit is the wiring portion of a system extending beyond the final overcurrent device protecting the circuit. Guidelines established in NEC, CEC, UL, and CSA should be used to determine the specific device. For example: ) Motor Branch Circuit Bulletin -A circuit breakers are not horsepower rated because they are able to safely interrupt currents far in excess of the locked rotor value for a selected motor. This ability is recognized in the codes and standards and is also established by the UL and CSA tests described in UL and CSA C. No. standards.

17 HACR Rating Bulletin -A s are rated as Heating, Air Conditioning and Refrigeration circuit breakers as defined by UL, paragraph. and may used in this type of application. SWD Rating The Bulletin breakers (. A) are rated as SWD and as such may be applied to switch fluorescent lighting loads up to their current and voltage maximum. Current Limiting Bulletin -A s are rated as current limiting circuit breakers as defined by UL, paragraph.. The Bulletin -A line features the ability to achieve short circuit interruptions far more effectively than conventional breakers. In conventional circuit breakers, the short circuit interruption time required is approximately one or two half cycles of an AC sine wave. When the contacts open, the resulting arc continues to burn until the current level passes through zero. The arc may re-ignite because of the insufficient width of the contact gap. The current that flows until the arc is extinguished produces a heating effect proportional to the It value (let-through-energy) of the fault current. The Bulletin -A device is designed to substantially reduce the amount of let-through-current and the resulting let-through-energy that can damage protected components. The Bulletin has the ability to interrupt short circuit current within the first half cycle of the fault. Limiting let-through current and energy will protect against the harmful effects of overcurrent and is focused primarily on avoiding the following: Excessive Heat Mechanical Damage Both of these factors are proportional to the square of the current. Thermal energy is proportional to the square of the RMS value and magnetic forces are proportional to the square of the peak value. The most effective way to provide protection is to substantially limit let-through-energy. This provides the following advantages Far less damage at the location of the short circuit. Fast electric separation of a faulty unit from the system, especially power supplies connected in parallel that are switched off when the voltage of the power bus drops below a certain level. Far less wear on the miniature circuit breaker itself. This means more safe interruptions. Better protection of all components in the short circuit path. Far wider range of selective action when used with an upstream protective device. (No nuisance shut downs from feeder line interruptions, causing a blackout in all connected branches.) The following values are applicable to the whole product range with frequency of / Hz. The values were derived from worst case V AC testing of: D trip A, V ka D trip A, Y/V ka D trip A, Y/V ka Current-Limiting at V / kap, p, p It = ka²s and I peak =. ka Current-Limiting at Y/V / ka p, p, p It = ka²s and I peak =. ka Current-Limiting at Y/V / ka p, p, p It = ka²s and I peak =. ka Bulletin -A Product Description Bulletin -A Ambient Temperature Derating The standard tripping characteristic for Bulletin -A is Type C. Type C has a magnetic trip activated at times the rated current of the circuit breaker. The reference temperature for the thermal tripping characteristics is C. The Type C characteristic will suit most applications.

32 Bulletin -D Product Description Description Bulletin -D s for Branch Circuit protection are available in - and -pole construction and are rated... A at V DC and... A at V DC for North American applications (UL and CSA C. No. ).. For EN\IEC applications the products are rated -pole:... A, V DC, and -pole:... A, V DC. Thermal Magnetic s The Bulletin -D Thermal Magnetic s are generalpurpose devices suitable for the majority of industrial, inverse time circuit breaker applications. They combine thermal and magnetic trip actions and provide accurate overload and short-circuit protection for conductors and connected equipment. Application Information Selection of a Bulletin -D circuit breaker with appropriate circuit protection includes consideration of: Circuit voltage Available short circuit current Continuous current rating Application considerations Special operating conditions Regional certifications The following discussion is based upon National Electric Code and UL requirements. Similar considerations are appropriate for Canadian and IEC applications. Circuit Voltage The Bulletin -D circuit breakers are rated by voltage class. Applications should not exceed the listed voltage and current range (see Table ). Available Short Circuit Current The Bulletin -D circuit breakers should only be applied in those applications in which the available short-circuit (or fault) current is less than or equal to ka. Table. Voltage and Current Ranges Region EN/IEC Regions North America (UL & CSA C. No. ) Max. Voltage Current Range [A] -pole V DC... -pole V DC... -pole V DC... -pole V DC... Continuous Current Rating Standard current ratings are:,,,,,,,,,,,,,,, and A. The Bulletin -D circuit breakers are rated in amperes at a C ( F) ambient temperature per the UL (CSA. No. ) standard. This temperature is generally used as the average temperature within an industrial enclosure. If a circuit breaker is applied in a temperature that exceeds the C ( F) ambient, then the circuit breaker should be derated. For IEC - standard, the products carry an ambient rating of C. Follow standard IEC application considerations for temperature rating in different ambient temperatures. The characteristic trip curve is shown on page -. The trip bands shown for each breaker represent current tripping limits for a circuit breaker and are within the limits established by UL. For a specific current at C ( F), a circuit breaker will open ("clear the circuit") automatically at some total time that will be within the "Minimum" and "Maximum" time shown on the curves. For example, page - shows that a one-pole, A, Bulletin circuit breaker trips in not less than s and not more than s on a A current. Because the UL standard defines this time spread, users should not specify exact tripping time. The lower current portion of the curves (upper left) depict the time to trip due to thermal action and reflect overload protection of the wire and connect load. The higher current portion of the curves (lower right) depicts the trip due to magnetic action of the circuit breaker and reflects protection due to short circuit level currents. Application Considerations The following is a discussion of application considerations related to North American applications. When applying product to IEC regional requirements, follow IEC practices and guidelines. The selection of a specific ampere rating for a specific application is dependent on the type of load and duty cycle and is governed by the National Electric Code (Canadian Electric Code) and UL/CSA. In general, the codes require that overcurrent protection is at the current supply and at points where wire sizes are reduced. In addition, the codes state that conductors be protected according to their current carrying capacity. There are specific situations that require application consideration, such as motor circuit, and guidelines for the selection for transformer protection. The Bulletin -D circuit breakers are non percent rated as defined by UL, para... As such, the circuit breaker's rating should be loaded to no more than % if used with continuous loads. Polarity Positive and negative connection many not be reversed. Branch Circuits Bulletin circuit breakers may be used to protect branch circuits. A branch circuit is the wiring portion of a system extending beyond the final overcurrent device protecting the circuit. Guidelines established in NEC, CEC, UL, and CSA should be used to determine the specific device. Coordinated Overcurrent Protection Where an orderly shutdown is required to minimize the hazards to personnel and equipment, a system of coordination based upon the faulted or overloaded circuit is isolated by selective operation of only the overcurrent protective device closest to the overcurrent condition. The user should select devices that meet this requirement. References: NEC.. Also see CEC. - Publication A-CAA-EN-P

33 Determining Ratings The tripping characteristic for Bulletin -D is Type C. Type C has a magnetic trip activated at times the rated current of the circuit breaker. The reference temperature for the thermal tripping characteristics is C ( F). The Type C characteristic will suit most applications.

Undervoltage trip is often used when loss of power and eventual restoration of power creates an unsafe or unknown set of condition. Shunt trip module Use the shunt trip module to trip the adjacent breaker poles from a remote location. The module is actuated by applying a voltage (pickup voltage) to the trip terminals. Shunt trip modules are often used in emergency shutdown circuits where multiple power circuits must be switched off from a single location.
