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