The PKZ2ZMR-0.6/S is a combination of the PKZ2/ZMR-0.6/S.
manual motor protector and the S-PKZ2 high capacity
magnetic con/tactor.
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
means that a group of motors, each protected and
controlled by
PKZ2/ZMR-0.6/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.
