BW-ABS Thermal Fuse with 0-250℃ Temperature Range Voltage & Current Protection and Small Internal Resistance

BW & BH series thermal fuses provide reliable protection against over-current and over-temperature conditions. These sealed units feature small internal resistance, silent operation, and automatic reset functionality. The temperature and current-sensitive bimetal components respond to abnormal conditions by changing state to either cut off or restore the circuit.

BH series protectors offer enhanced safety with immediate response to sudden current surges, eliminating temperature effect lag.

BH series thermal protectors serve as effective security devices for:

• 1.5 horsepower motors
• Lighting devices
• Inverter welding machines
• Switch power supplies
• Rechargeable battery packs
• Fluorescent lamp ballasts
• Portable power tools
• Various electric appliances

Enforced types (withstanding 3.5MPa pressure) are suitable for plastic-coated motor installations.

These universal protectors feature large metal casings containing:

• Thermal conductive metal casing
• Bimetallic components with silver alloy contacts
• Conductive bracket
• Insulation fixation stand
• Fixed contact strip
• Heat resistance cable

During abnormal operation, rising temperatures trigger the bimetallic components to open contacts and interrupt the circuit. Automatic reset occurs when temperatures return to safe levels.
