For more inductive loads - high inrush currents The PKZMO-...(-T) is 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. The PKZMO-...-T has its magnetic trip set at high response level to provide better protection against nuisance tripping in circuits with higher current inrush ratings, e.g. in circuits employing control circuit transformers. The PKZMO... and PKZMO-...-T are UL listed 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 means that a group of motors, each protected and controlled by a PKZMO-...(-T) can be combined under a single branch circuit short circuit and ground fault protective device, the maximum rating of which is marked on each PKZMO motor protector. | ||||||||
