18AM-B resettable Thermal Cutoff Switch / norally oncircuit protector with enforced metal caseDescription:
Changsheng 18AM-B with enforced metal case 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.
Wall thickness of the enforced case is 0.5m minimum and it will withstand 30MPa injection pressure (no deformation).
