BR-B5D Small AC Thermal Protector / Thermal Overload Protection For
Motor
Description:
Changsheng BR-B2D 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 plastic PBT housing that holds
and protects the inner components against infiltration as well as
mechanical deformation. In single–phase motors, the BR-B2D can be
mounted directly in the main circuit to serve as an on– or
in–winding protector.
