BW-ABJ BW-ABS 10 Amp Resettable Fuse KW9700 Thermal Protection Switch with 50-150℃ Range 100000 Cycles Plastic Case

The BW & BH series protectors offer reliable over-current and over-temperature protection with automatic reset functionality. These sealed units feature small internal resistance, operate silently, and automatically reset when conditions normalize. The temperature and current-sensitive bimetallic components change state to either cut off or restore the circuit during abnormal conditions.

BH series protectors provide enhanced safety with no temperature effect lag during sudden current surges, making them superior to standard protectors.

These snap-action thermostats serve as effective, reliable security protectors and alarm devices for various applications including:

• 1.5 horsepower motors
• Inverter welding machines
• Switch power supplies
• Fluorescent lamp ballasts
• Portable power tools
• Electric appliances and equipment

Enforced types capable of withstanding 3.5MPa pressure are suitable for plastic-coated motor installations.

The H20 and H21 series universal and enhanced protectors feature large metal casings containing thermal conductive metal components, bimetallic parts with silver alloy contact points, conductive brackets, insulation stands, and heat-resistant cables. During abnormal operation, rising temperatures trigger the bimetallic components to quickly open the contacts and disconnect the circuit. Normal operation automatically resumes when temperatures return to safe levels.

These protectors are suitable for use in:

• Chargeable batteries
• Ballasts
• Massagers
• Micro motors
• Transformers
• Electric tools
• Heat electric appliances and instruments
