BH series thermostat / Miniature thermal protector / Rechargeable battery thermostat
BH Series Thermostat - Principle and Structure
BW & BH series protectors offer reliable protection against over-current and over-temperature conditions. These sealed units feature small internal resistance, operate silently, and reset automatically. When current flows through the temperature and current-sensitive bimetal, abnormal conditions cause the bimetal to change state, either cutting off or restoring the circuit. BH series provide enhanced safety compared to standard protectors, with no temperature effect lag during sudden high-current events.

BH Series Thermostat - Applications and Instructions
BH series thermal protectors serve as effective, reliable security protection and alarm devices. They are widely used in: 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, H21 Series Thermostat - Principle and Structure
H20 and H21 series universal and enhanced protectors feature large metal casings and are composed of thermal conductive metal casing, bimetallic components welded with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat resistance cables. During abnormal operation, when environmental temperature reaches the set value, the bimetallic components perform quick action, opening the contacts and disconnecting the circuit. When the device cools to safe operating temperature, the contacts automatically close and normal operation resumes.
