Moeller PKZ2/ZMR-xx/S-SP Manual Motor Starter Overview

Under overlaod and short-circuit fault conditions the standard trip module will open the main disconnect portion of the PKZ2 Self-protected Starter, much like the operation of an inverse time molded case breaker. As an option, the trip module type ZMR can be provided. It features a set of auxiliary contacts which are activated under overload conditions.
Similar to the operation of an overload relay in a conventional combination controller, the N.C. contact can be used to de-energize the contactor coil circuit in the event of an overload and N.O. contact can be used to annunciate the condition. A short-circuit fault will trip open the main disconnect instantaneously, just like the standard trip module.

The ZMR module is is ideal for applications which need to take full advantage of the self-protected starter’s capabilities over conventional combination controllers, but wish to retain the operating features of a conventional overload relay in a starter.
