BH-TB02B-B8D mini temperature sensor protector
BW9700温控器产品是一种用双金属片作为感温元件的温控器，电器正常工作时，双金属片处于自由状态，触点处于闭合/断开状态，当温度升高至动作温度值时，双金属元件受热产生内应力而迅速动作，打开/闭合触点切断/接通电路，从而起到热保护作用。当渐度降到重定温度是触点自动闭合/断开，恢复正常工作状态。
1. 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.
