Mini thermal protector fuse swtich BH-TB02B-B8D 250v 2a 30 to 150 degree with UL TUV CQC
BH series thermostat’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.
