For more inductive loads - high
inrush currents
The PKZM0-...(-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
PKZM0-...-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 PKZM0... and PKZM0-...-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 PKZM0-...(-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 PKZM0 motor protector. |
