The 37T Series Moisture Resistant Thermostat From Therm-O-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.The sealed design provides moisture resistance for moisture prone environments. A wide variety of terminal, lead wire and mounting configurations are available to provide maximum design flexibility. 

The 37T is the most popular and widely applied temperature control in refrigeration applications such as defrost termination and ice cube maker control. It is also applied in a range of heat pump and air conditioning applications.

The 37T features include:
Sealed construction provides moisture resistance for moisture prone environments.
High-speed contact separation ensures long contact life.
Controls are 100% operation checked and dielectric tested.

The 37T is available in two switch actions:
Automatic Reset Single Pole Single Throw (SPST)
Automatic Reset Single Pole Double Throw (SPDT)

The 37T is available in several mounting configurations:
No Mounting Bracket
Surface Mounting
