BH series mini thermal protector’s Principle and structure
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.
BH series mini thermal protector’s Application
It is widely applied for all kind of motors, lighting, inverter welder, switch power supply, heating appliance, rechargeable battery pack, transformer, rectifier, portable power tool, water pump, AC motor etc.
