Trip modules with overload relay function
ZMR-...- PKZ2 are inserted in the load side of the
motor protector disconnect handle. Similar to the
operation of an overload relay, the ZMR 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
just like the standard
ZM trip module. The ZMR 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 thermal and 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
