The PKZMO basic module 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.
Adding the SE00 high capacity motor contactor to the PKZMO forms a
combination motor starter.
The PKZMO may also be combined with our standard contactors.
Utilizing the special carrier and pre-wired jumper block it quickly
becomes a custom starter.
PKZMO motor protectors in
group motor applications:
PKZMO motor protectors are UL
listed and CSA certified for group applications as per the intent of NEC 430-53
and CEC part 1, rule 28-206. This eliminates the need for individual motor
branch circuit overcurrent protective devices for each motor, thus greatly
reducing the cost and space requirements of industrial control panels and
assemblies.
In group installations
involving a number of PKZMO motor protectors, the maximum rating of the group
branch circuit overcurrent protective device is based on the lowest backup
overcurrent rating marked on each motor in the group, combined with applicable
NEC-CEC installation rules.
The PKZMO motor protectors
through 16A, have also passed additional UL tests and are marked "Suitable for
tap conductor protection in group installations". They can thus be applied
for tap conductor overcurrent protection in group installations per the intent
of Article 430.53 of the NEC 2002.
