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: DC-12V max 12A; DC-24V max 10A; AC-125V max 8A; AC-250V max 5A
• BH-TB02 Series: DC-12V max 4A; DC-24V max 3A; AC-125V max 3A; AC-250V max 2A

• Open Temperature: (30~150)±5°C; 5°C increments
• Reset Temperature: 2/3 of action temperature with ±15°C tolerance
• Custom reset temperatures available per customer requirements

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.
