5 MAG-GARD Motor Circuit Protectors Selection Table Class 6 Square D Adjustable Instantaneous-trip Circuit Breakers for Single Motor Circuit Protection Based on NEC Article 4- and NEC Table 4-.

HP s of Induction Tpe Squirrel-cage and Wound Rotor Motors Three-Phase Hz ac 4 * Full Load s MAG-GARD Circuit Breaker No. Magnetic Trip Settings t MIN MAX GL Famil MAG-GARD Circuit Breaker No. Magnetic Trip Settings t MIN MAX Adjustable instantaneous-trip circuit breakers are intended for use in combination with motor starters with overload relas for the protection of motor circuits (rqm [ short circuits. Other specific applications include rectifiers and resistance welders. These circuit breakers contain a magnetic trip element in each pole with the trip point adjustable from the front. Interrupting ratings are determined b testing the instantaneous trip circuit breakers in combination with a contactor and overload rela. Select instantaneous trip circuit breakers as follows:. This selection table is suitable for motors, other than NEMA Design E, with locked-rotor indicating code letters per NEC Table 4-7 (b) as follows: Horsepower V or less *4 to 'A to 0 0 or more Motor Code Letters A-L A-K A- A-H A-G A-F For other motors order a special thermal magnetic circuit breaker with magnetic trip settings for the specific motor - specif motor horsepower, voltage, frequenc, full-load current and code letter or locked rotor current. i. Determine motor HP rating from the motor nameplate.. Refer to the table at right and select an instantaneous trip circuit breaker with an rating recommended for the HP and voltage involved. 4. Select an adjustable trip setting of at least, not to exceed, of the motor full-load s. (FLA) for other than Design E motors. For Design E motors, select an adjustable trip setting of at least % not to exceed of FLA.. The NEC maximum setting ma be inadequate for instantaneous trip circuit breakers to withstand current surges tpical of the magnetization current of autotransformer tpe reduced voltage starters, or open transition we-delta starters during transfer from "start" to "run", constant HP multi-speed motors, and motors labeled "high efficienc". Select thermal-magnetic circuit breakers from Page 6-8 for those applications. 6. Part-winding motors, per NEC 4-, should have two circuit breakers selected from the above at not more than one half the allowable trip setting for the horsepower rating. The two circuit breakers should operate simultaneousl as a disconnecting means per NEC 4-0. * Motor full-load currents are taken from Table 4- of the NEC. Select wire and circuit breakers on basis of horsepower rather than nameplate full-load current per NEC Article 4-6 (a) for general motor applications. Do not use these values to select overload rela - thermal units. See Digest 7, Page ---9 for selection of thermal units when actual full load is not known. The voltages listed are rated motor voltages. Corresponding nominal sstem voltages are to 8, 0 to, 4 to 4 and to volts. A See NEC Section 4-(a) for breaker settings above. It due to motor starting characteristics, trip settings at the maximum permitted level are needed, the next size MAG-GARD circuit breaker should be chosen. t Onl MIN and MAX settings are shown, intermediate settings are available on all circuit breakers. 7'. 0 Vfe t V4 7V6 0 0 V4 4 V4 7V V 4 V FAL-M* FAL- M* FAL- M FAL- M FAL-M FAL-M FAL-M FAL-M" I " FAL-M FAL-M FAL-M FAL-M FAL-M FAL-M FAL-M FAL-M FAL-M FAL-M FAL-M FAL-6M FAL-6M FAL-6M FAL-6M FAL-6M FAL-6M FAL-6M FAL-6M FAL6-8M FAL6-8M FAL6-8M FAL6-8M FAL6-8M FAL6-8M FAL6-8M FAL6-8M FAL6-4M FAL6-4M FAL6-4M KAL-M KAL-M KAL-M KAL-6M KAL-9M KAL-9M KAL-9M KAL-9M KAL-M KAL-M KAL- M KAL-M KAL-M KAL-M KAL-M LAL6-M LAL6-M LAL6-M LAL6-M LAL6-6M LAL6-6M LAL6-6M LAL6-6M MAL6-M MAL6-M MAL6-M MAL6-M MAL6-M MAL6-M MAL6-44M MAL6-44M MAL6-44M MAL6-4M MAL6-4M MAL6-4M 0% % 0% 0% 0% 0% % 0% 0% % % % % % % % % 0% % % % 0% % % % % % % % 0% % A A * B " GLM0 GLM0 GLM0 GLM0 GLM0 GLM0 GLM0 GLM04 GLM04 GLM04 GLM04 GLM04 GLM04 GLM04 GLM0 GLM0 GLM0 GLM0 GLM0 GLM0 GLM0 % % % 0% 0% 0% 0% 4% 0% % % % % % % 0% % % % % % % % 0% 0% 'Vliiw -i..
