Plug-on thermal motor protector for compressors
Protects compressors for refrigerators, freezers, dehumidifiers, water coolers, vending machines, and similar refrigeration applications
Compatible with PTCR starters and electromechanical relays
Product designed and manufactured in an enviroment of Total Quality Control
Applicable to compressors manufactured around the world
Conforms with worldwide certification agency standards
When the disc snaps, it actuates the spring arm located above the disc, opening the contact circuit which shuts off the compressor motor. The operating parameters of the 4TM are not affected by contact wear because the contacts are not part of the resistance circuit and are not part of the temperature calibration mechanism. The design features of the 4TM performance and reliability are the following:
The variability to increase offtimes allows for matching and compatibility with PTCR starters
Reduced temperature drift over life cycles
Repeatability of trip time and ultimate trip
Resistance to physical and thermal shock
