Combining the PKZ2 basic module with a ZM-xx-PKZ2 trip module forms a 3 phase thermal magnetic motor protective device incorporating adjustable bimetal trips for motor overload protection and magnetic trips to de-energize the motor circuit in case of a short circuit. Adding the S-PZZ2 high capacity motor contactor to the PKZ2/Zm-xx forms a combination motor starter. |

| The PKZ2-ZM-../S is a
combination of the PKZ2/ZM-... manual motor protector
and the S-PKZ2 high capacity magnetic contactor. UL listed and CSA certified as HP rated motor controllers which provide motor running overload protection. In addition, they are UL listed and CSA certified for group applications as per NEC 430-53(c) and CEC part 1, rule 28-206. This eliminates the need for individual motor branch circuit over current protective devices for each motor, thus greatly reducing the cost and space requirements of industrial control panels and assemblies. This manes that a group of motors, each protected and controlled by PKZ2/SM...(/s) can be combined under a single branch circuit short circuit and ground fault protective device, the maximum rating of which is marked on each PKZ2 motor protector. In group installations involving a number of System PKZ2 motor protectors, the maximum rating of the group branch circuit over current protective device is based on the lowest backup over current rating marked on each motor protector in the group, combines with applicable NEC/CEC installation rules. |
