Snap–Action Disc Motor Thermal Overload Protection / Thermal Cut Out Switch
Applications:
Description:
Changsheng BR-A1D series motor protector is built to meet almost any requirement of protection in a wide range of small motors, small transformers, solenoids, and more. This compact motor protector is the best solution to protect the wide variety of motors under 1 Hp used in industrial and domestic appliances against locked rotor and overload situations.
This motor protector consists of a metal SPCC housing that holds and protects the inner components against infiltration as well as mechanical deformation. In single–phase motors, the BR-A1D can be mounted directly in the main circuit to serve as an on– or in–winding protector.
