Description
Bimetallic Strip Thermal Overload Protector Switch For Electric Heater
BW thermal protectors for electric heater
Principle and Structure
Bimetallic Strip Thermal Overload Protector Switch For Electric Heater
BW series thermal protector uses a specific geometry of bimetallic strip that, without auxiliary mechanisms, directly senses mild heating current. The bimetallic element rapidly changes state to automatically drive contact cutting and process circuit functions, providing both overheating and overload protection.
Applications
Widely applied in electric motors and electrical equipment including: electric blankets, hot walls, washer motors, soybean milk machine motors, fan motors, air conditioner motors, fractional motors, DC motors, AC brushless motors, water pumps, transformers, rectifiers, lighting systems, rechargeable batteries, and electric heating appliances.
