Thermal protection relay contactor 4TM1/8 L, 220 V
Model: 4TM1/8 L
Voltage: 220 V
Connection: 1 terminal 6.3 mm + twist contact "female"
Dimensions: 29x31.5x22.5 mm
Description
The thermal protection relay contactor 4TM1/8 L is designed to protect refrigerator compressors from overheating and overloads. It automatically opens the circuit when critical parameters are reached, preventing damage, and restores the device's operation once normal operating conditions are resumed.
Operating principle:
- When powered on, the relay connects the compressor to the power supply.
- In case of overheating or overload, the circuit opens, disconnecting the compressor.
- After cooling down or resolving the overload, the relay returns to its original state.
Main specifications
