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.
