Product Description
Metal / Plastic Case Motor Thermal Overload Switch Small Size RoHS Approved
KW thermal motor protector - Metal / Plastic Case Motor Thermal Overload Switch Small Size RoHS Approved
Principle and Structure
BW series thermal protector utilizes a specifically designed bimetallic strip geometry. Without auxiliary mechanisms, the bimetallic strip directly senses heating current and rapidly changes state to automatically cut the circuit, providing both overheating and overload protection.
Applications
Widely applied in electric motors and electrical equipment including:
- Electric blanket and hot wall appliances
- Washer motor and soybean milk machine motor
- Fan motor and air conditioning motor
- Fractional motor and direct current motor
- AC brushless motor and water pump
- Transformer and rectifier
- Lighting and rechargeable battery systems
- Various electric heating appliances
