INT69 52A 120 S10 motor protector Bitzer compressor protection module

Introduction:

It is used to monitor the compressor motor winding temperature, exhaust temperature, power phase sequence and phase loss fault in the refrigeration system.

It must be used together with the PTC thermistor to prevent the motor temperature and exhaust temperature from being too high.

It can monitor 1-9 series PTC thermistor values in the motor. If one or more PTC resistors are in high impedance state, the motor protector relay releases and self-locks.

Features:

1, The phase sequence monitoring function is enabled within 5S after power-on. Once the phase sequence is faulty, the relay switch is disconnected and self-locking.

2, After the motor starts 1S, the phase loss monitoring function works. Once the phase loss fault is detected, the motor is turned off; after 10S, the automatic reset is monitored again; if the phase loss fault is detected three times in 12 minutes, or 10 phase loss is detected in 24 hours. If the fault occurs, the protector is automatically locked.
