BH series thermostat / Miniature thermal protector / Rechargeable battery thermostat
BH series thermostat’s Principle and structure
BW & BH series that can protect against over-current and over-temperature are sealed firmly, small internal resistance, no noise and reset automatically. When current through bimetal that are sensitive to temperature and current, the status of the bimetal will be changed by over-temperature or over-current to cut off circuit or switch on circuit. BH series are safer than normal protectors, as there is no temperature effect lag under condition of sudden big current.

Bimetallic Thermal Switch , Thermal Cutoff Switch BW-A1D250v 5a-16a 50-150c
BW serial universal and enhanced protectors with large metal casing are composed of the thermal conductive metal casing, bimetallic parts welded with silver alloy contact point, conductive bracket, insulation fixation stand, fixed contact strip and heat resistance cable. In case of abnormal operation, along with the increase of the environment temperature to the set value, the bimetallic parts perform quick action, open the contact point, and disconnect the circuit. When the device is cooled to the temperature for safe operation, the contact point will automatically closes and recover normal operation.
