Thermal protective relay contactor 4TM1/4 X2, 220 V

Model: 4TM1/4 X2

Voltage: 220 V

Connection: 2 terminals 6.3 mm + twist contact "female"

Dimensions: 29x31.5x22.5 mm

Description

The thermal protective relay contactor 4TM1/4 X2 is designed to protect refrigerator compressors from overloads and overheating. It automatically disconnects the compressor when critical conditions are reached, preventing damage and extending the device's lifespan. The relay restores operation once conditions normalize.

Operating principle:

1. The relay activates when power is supplied to the compressor, ensuring its operation under normal conditions.
2. In the event of an overload or overheating of the compressor, the relay opens the circuit, preventing damage to the device.
3. Once conditions normalize, the relay automatically returns to its original state.
