2 January 0 Vol., Ref. No. [0] Types A07, A08 and A09 8- Product Selection Product Selection for Manual Starter Applications When ordering, specify Catalog Numbers according to the following stipulations: A07, A08 and A09 starters are selected based on the overload current range required for a given motor. This current range is determined from the motor Full Load Ampere rating and Motor Service Factor usually found on the motor nameplate. For motors with service factors less than., multiply the motor FLA by.9 to select appropriate starter. Example: For motor having FLA of 6.4A and service factor of.0 (6.4A x.9 =.88A) select Catalog Number A07TN. For motor with service factor of. or greater, use motor nameplate Full Load Amperes to select the appropriate starter. Example: For motor having FLA of 6.4A and service factor of., select Catalog Number A07UN. Table 8-.

No. [0] 8 Contents Description Page Manual Motor Starters & Protectors Product Description Application Description Features Standards and Certifications Technical Data Accessories Wiring Diagrams Time/Current Curve Dimensions Product Selection Type A07, A08 and A09 Product Description The A07, A08 and A09 family of feature a rotary ON/OFF manual disconnect, Class adjustable bimetallic overload relay and fixed magnetic short circuit trip capability in one compact unit. Three frame sizes are available: A07 (4 mm) for motors with FLA ratings up to A, A08 ( mm) covers motor FLA ratings up to 0A and the A09 (70 mm) is suitable for motor FLA ratings to 0A. Group Motor Installations A Group Motor Installation can be defined as more than one motor circuit protected by a single set of fuses or circuit breaker on a motor branch circuit. This eliminates the need for individual fuses or circuit breakers for each motor circuit. Substantial component cost savings, panel space savings and reduced wiring installation time can be achieved in Group Motor Installations. The A07, A08 and A09 Manual Motor Starters and Protectors are UL Listed for Group Motor Installations and have a short circuit current rating of 0 ka at 480V and ka at 600V. If remote operation is required, a magnetic contactor can be wired in series with the Manual Motor Starter and Protector. See Figure 8-6 below. Article - of the National Electric Code contains the rules and requirements for Group Motor Installations. The following are general rules from NEC Article - for sizing the Branch Circuit Protective Device (BCPD) for a Group Motor Installation. These general rules are to be used as a guide only, and not as a substitute for the actual requirements stated in the National Electric Code. Application Description The A07, A08 and A09 Manual Motor Starters and Protectors can be used in the following applications: Manual Starter All of the Manual Motor Starters and Protectors are UL Listed under UL08 as Manual Motor Controllers. They provide an economical solution for applications requiring simple manual starting and stopping of motors. When used as a Motor Starter, they are typically installed in an enclosure. IP enclosures are offered as accessories for the. Separate short-circuit protective devices, such as circuit breakers or fuses, are wired ahead of the Manual Starter and Protector. The short-circuit protective device should be sized per the NEC code and should not exceed 0% of the maximum FLA dial setting of the Manual Starter and Protector. Manual Motor Starter and Protector Selection A Manual Motor Starter and Protector is required for each motor in the Group Installation and is selected by motor FLA as described on Page 8-4.

4 January 0 Vol., Ref. No. [04] Types A07, A08 and A09 8- BCPD Selection for Group Motor Installation A circuit breaker or single set of fuses can be used on a Branch Circuit of a Group Installation. Cutler-Hammer recommends the use of Cutler-Hammer Molded Case Circuit Breakers whenever possible for Group Motor Installations. Sizing BCPD for Group Motor Installations If a circuit breaker is used for BCPD in a Group Motor Installation, the following formula should be used: Max. Circuit Breaker = Largest Motor FLA x % + FLA of all other motors in Group. If fuses are used for BCPD in a Group Motor Installation, the following formula should be used: Max. Fuses = Largest Motor FLA x 7% + FLA of all other motors in Group. Single Motor Taps NEC Article - (d) This NEC Article restricts the size of the BCPD based on the wire sizes used for the application. The BCPD must protect the wires used. This section of the code should be reviewed before selecting a BCPD size. Important Application Notes It is important to note that not every multi-motor application is a good candidate for the Group Motor Installation approach. The frequency and severity of potential short circuit conditions for each application should be analyzed by the customer before deciding if the Group Motor Installation approach is appropriate. Self-Protected Manual Combination Starter (UL08, Type E) A07, A08 and A09 Manual Motor Starters and Protectors are also UL Listed as UL08, Type E, Self-Protected Manual Combination Starters. This UL Listing allows these devices to be used in motor circuits without having to add separate short circuit protection upstream. These devices have a short circuit rating of 0 ka at V and 480Y/77V. Component in a Combination Starter The A07, A08 and A09 Manual Motor Starters and Protectors can also be wired in series with a magnetic contactor to complete the assembly of a remotely operated, combination starter. Circuit Breaker In many countries outside of the United States and Canada, especially Europe, the Manual Motor Starters and Protectors are tested and classified as thermal magnetic circuit breakers for use in motor branch circuits. This can be an important consideration for all companies who export their equipment and machines internationally.
