The 4TM Thermal Motor Protector Refrigerator Overload Protector is an essential device that provides reliable protection against overload and overheating. Its automatic shut-off feature, easy installation, compact design, and high-quality construction make it an excellent choice for anyone looking to protect their refrigerator compressor from damage.
The basic function of the 4TM is to protect the motor in a refrigeration compressor from overheating, resulting from locked rotor or running overload conditions. The 4TM provides this protection by sensing the current and temperature of the motor. The fundamental actuation principle incorporates a noncurrent carrying snap-acting disc, which is located above the heater element.
