KSD9700 Auto Reset Thermal Fuse Bw-abs Temperature Controller KW9700
Bimetal Temperature Switch, Temperature Protector BH-B2D 250V 5A 30-150°C
BW & BH series thermal protectors are sealed firmly and feature small internal resistance, no noise, and automatic reset functionality. When current passes through the temperature and current-sensitive bimetal, the bimetal's status changes due to over-temperature or over-current conditions, either cutting off or switching on the circuit. BH series protectors are safer than standard protectors as there is no temperature effect lag under sudden high current conditions.

BH series thermal protectors serve as effective, reliable security protectors and alarm devices. They are widely used in:
- 1.5 horsepower motors
- Lighting devices
- Inverter welding machines
- Switch power supplies
- Rechargeable battery packs
- Fluorescent lamp ballasts
- Portable power tools
- Electric appliances and other electrical equipment
These protectors prevent damage from over-current and over-heating caused by abnormal working conditions. Enforced types capable of withstanding 3.5MPa pressure are suitable for built-in installation in plastic coated motors.
