ST11 ST06 ST01 ST05 Temperature Protector KW Temperature Controlled Switch

BH series thermostat / Miniature thermal protector / Rechargeable battery thermostat

BW & BH series protectors provide reliable protection against over-current and over-temperature conditions. They feature sealed construction, small internal resistance, silent operation, and automatic reset functionality. When current flows through the temperature-sensitive bimetal component, abnormal conditions cause the bimetal to change state, either opening or closing the circuit as needed. BH series offer enhanced safety compared to standard protectors, with no temperature effect lag during sudden high-current conditions.

BH series thermal protectors are effective, reliable security protection and alarm devices 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 operating conditions. Enforced types capable of withstanding 3.5MPa pressure are suitable for built-in installation in plastic-coated motors.

H20 and H21 series universal and enhanced protectors feature large metal casings and consist of thermal conductive metal casing, bimetallic components with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat-resistant cables. During abnormal operation, when environmental temperature reaches the set value, the bimetallic components perform quick action to open contacts and disconnect the circuit. When the device cools to safe operating temperature, contacts automatically close to restore normal operation.

H20 and H21 series are suitable for rechargeable batteries, ballasts, massagers, micro motors, transformers, electric tools, heating appliances, and instrumentation.

All products feature UL, CQC, TUV and RoHS certification approval.
