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
