4 149-CB Bulletin 149 Circuit Breakers (Supplementary Protectors) Trip Curves 149-CB Trip Curves are available in publication The Benefits of Limiting Let-Through-Energy Description Bulletin 149 Energy Limiting circuit breakers are thermal magnetic type supplementary overcurrent protective devices. Bulletin 149-CB circuit breakers are available in 1-, -, and 3-pole units rated from A. AC units are rated as standard. - and 3- pole devices are connected internally and at the handle for simultaneous operation. Wire termination is achieved by a clamping style, self-lifting box lug on all Bulletin 149-CB units. Both line and load side termination points will accept #16 6 AWG ( mm ) copper wires. Features Energy Limiting Design protects downstream components better than conventional breakers during short circuits Field-mountable options for selective applications True IPX Finger-Safedesign(topand sides) International approvals CE Marked, meets UL, CSA, and IEC (VDE) standards for worldwide acceptance Ratings to 480V AC and 10,000 A Interrupt Capacity (refer to page 1-98) AC and DC voltage ratings in one convenient device A positively trip-free mechanism (breaker operation cannot be defeated by holding the handle in the ON position) 3tripcurves:F,G,andH Time delay (H characteristic) for high inrush currents during inductive start-ups such as transformers and power supplies Superior shock and vibration resistance capabilities helps to prevent nuisance tripping Mounts on DIN Rail or optional through door brackets On standard AC/DC versions (F, G, H) line and load connections may be reversed Short Circuit Interruption Diagrams VOLTAGE ACROSS BREAKER CURRENT CONVENTIONAL BREAKERS Short Circuit Interruption 10 ka 10 Volts AC Instant of initiation: 15 after voltage zero TIME A B C A B C A = Instant when the short is initiated B = Instant when the contacts open and the arc is initiated C = Instant when the arc extinguishes and the current ceases to flow 149-CB vs. Conventional Breakers The 149-CB line features the unique ability to achieve short circuit interruptions far more effectively than conventional breakers. In conventional circuit breakers, 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 I tvalue (let-through-energy) of the fault current. The 149-CB Energy Limiting circuit breaker is designed to substantially reduce the amount of let-through-current and the resulting let-through-energy that can damage protected components. The 149-CB has the ability to interrupt short circuit current within the first half cycle of the fault.

5 Bulletin CB, Continued The Benefits of Limiting Let-Through-Energy (Continued) Limiting let-through-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. Thisprovidesthe 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 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.) Applications Bulletin 149-CB Energy Limiting circuit breakers have a wide range of trip characteristics for a wide range of applications. F trip characteristic (3 5 x In) ➊ for low fault tolerant loads, such as PLC outputs, solid state control equipment, and also for selective action with an upstream fault device G trip characteristic (6 10 x In) ➊ for standard duty loads, such as relay coils, control circuitry, and test equipment H trip characteristic (1 0 x In) ➊ for high inrush loads, such as power supplies, heaters, and transformer primaries A type F has a fault level inrush current interruption approximately half that of type G. The type H has a fault level interruption approximately twice that of type G Accessories Accessory Notes Note:Maximum of two accessories per device. Auxiliary Contacts Refer to Specifications on page 1-97 for ratings. Each auxiliary contact module contains one (1) contact, either Normally Open ornormally Closed.Actuation ofthe contact is determined by the handle position of the adjacent poles. Signal Contacts Refer to Specifications on page 1-97 for ratings. Each contact module contains one contact that will be linked internally with the adjacent poles, but not through the handle. Contacts are actuated by a fault condition on the protected poles, not by the manual operation of them. Note: The difference between an auxiliary contact and a signal contact is the protected poles adjacent to the signal contact may be manually shut off without affecting the status of the signal contact, whereas the auxiliary contact is activated either by manual (possibly to service a panel) or automatic operation (fault) of the protected poles. Manual operation of the protected poles does not alter the contact state of the signal contact (which may be connected to an alarm circuit for fault indication only). ➊ In = rated current. The time/current trip characteristic k1 k x In is defined such that inrush current k1 x In has a time delay that exceeds 10 ms, and k x Inhasatime delay that is less than 10 ms. Relay Trip (Shunt-Trip) Refer to the table below for ratings. The Relay trip module can be used to trip the adjacent current carrying poles from a remote location by applying a voltage (pick-up voltage) to the Relay trip terminals. Contacts operate between 8 and 16 milliseconds after the pick-up voltage has been applied. Type Pick-Up Voltage Range Impedance A V AC/DC 1.1 Ω A 10 4V AC/DC 4.7 Ω A3 0 48V AC/DC 16 Ω A V AC/DC 63 Ω A V AC/DC 395 Ω Switched Neutral Module (not field-mountable) Refer to Specifications on page 1-97 for ratings. This module is used to open the neutral line of the circuit as a result of the condition of the protected poles. It is used as a safety measure (required by some standards) for the protection of networks with a grounded neutral system. The switched neutral pole opens after and closes before the adjacent protected pole (i.e., early make, late break). Automatic actuation is a result of the adjacent pole trip mechanism and manual actuation is by the linked handles.

6 149-CB, Continued How to Order 149-CB The following information must be known to select the proper circuit breaker: What is the full load amperage that will be available in the system? Is it a 1-, -, or 3-phase system? What are the start-up or inrush properties of the load? Will the system require additional shaping options (e.g., auxiliary contacts, signal contacts)? After defining these few parameters, the selection can be done by following the chart below. All options are field-mountable except the neutral switch, which comes installed from the factory.

11 149-GH, Continued UL, CSA, and IEC Rated Selection Guide To select a circuit breaker use the following procedure: Determine the inrush correction factor from Table 1. Determine the temperature correction factor from Table. Determine the sealed current of the load being protected. Multiply the sealed current by the two correction factors and select the closest higher ampere rating. Example What size circuit breaker should be selected for a solenoid with sealed current of 0.5 A, an inrush ratio of 1:8, and an ambient temperature of +110 F (43.7 C)? 0.5x1.7x1.15= Select the 1.0 A circuit breaker.

These designations are defined as follows (see ➋ also): C Indicates that the short-circuit test was conducted with series overcurrent protection U Indicates that the short-circuit test was conducted without series overcurrent protection 1 Indicates that a recalibration and dielectric test was not conducted as part of the short-circuit test Indicates that a recalibration and dielectric test was conducted as part of the short-circuit test ➋ These alphanumeric designations were established by UL. CSA has not yet adopted them; however, the test conditions are equivalent to UL and the coding is appropriate
