MPR69 is suitable for mounting into the terminal box of an electric motor. It can be used for compressors such as FUSHENG, Copeland and Refcomp, etc.
The 41AA series protection relay is designed to protect against excessive motor winding temperatures by monitoring the resistance of positive temperature coefficient (PTC) thermistors embedded in the windings.
The SE-E1 motor protector relay is designed for screw compressors, monitoring of motor temperature, phase sequence and phase failure of motors.
PFR51/53 series are the monitoring relays used for three-phase three-wire systems or three-phase four-wire systems.
PFR55CM40 is the monitoring relay used for three-phase three-wire systems, monitors for under-voltage, over-voltage, phase sequence, phase loss and voltage unbalance.
PFR2000 used as a protector against the voltage unbalance, phase loss, phase reversal, overvoltage and undervoltage, and correct the phase automatically of the motor.
