Moeller ZM-40-PKZ2
Motor Protector Trip Block

Includes auxiliary contacts to de-energize contactor,
with Hand/Auto position

Trip modules with overload relay function are inserted in the load side of the motor protector disconnect handle.  Similar to the operation of an overload relay, the ZM-40-PKZ2 uses a set of auxiliary contacts to de-energize a contactor coil circuit and signal an overload condition.  A short circuit will trip open the motor protector like the standard ZM trip module. 

The ZM-40-PKZ2 is also supplied with a HAND/AUTO reset feature.  It cannot be combined with U/A voltage trips or RE/RS remote control drives.

FEATURES:

§ Adjustable and thermal magnetic trips set in accordance with the motor FLC.

§ Tamper proof lids that cover thermal and magnetic settings when the device is on

§ Ambient compensation

§ Phase failure sensitivity

§ Coding accessory to insure insertion of correct module for the motor rating
