Product Details

24V/12A BR-A1D DC Thermal Overload Protection , Thermal Cut-off Protector 250V 5A
 
 
Description:
 
Normally on and open on temperature increment
 
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.

 
 
Applications:

  • Small motors
  • Coils
  • Transformers
  • Washers and dryers  
  • Dishwashers
  • Automotive accessory motors
  • PC boards
  • Battery charges
  • ………and more.
