37T Moisture Resistant Bimetal Control

The 37T auto reset bimetal control from Therm-O-Disc® offers proven reliability in a moisture resistant design. The snap action of the bimetal disc provides high-speed contact separation resulting in excellent life cycle characteristics at electrical loads up to 10 amps at 120VAC and 5 amps at 250VAC, for temperature calibrations up to 300°F (149°C).  The 37T carries global agency recognition and is used in a wide range of applications including residential and commercial refrigeration, heat pumps, and air conditioning.
