BW-A1D Motor Thermal Protection Switch BH-B2D Overload temperature Protection with UL TUV KC CQC
BW series thermal protector’s Principle and structure
BW series thermal protector is to use a certain geometry of bimetallic strip, without auxiliary institutions, only by bimetallic strip their own sense of mild heating current, rapid changes in the state of bimetallic element, direct drive contact automatic cutting and processing circuit, overheat protection, overload protection.
BW series thermal protector’s application
It is widely applied in Electric motors and electrical equipment as electric blanket, hot wall, washer motor, soybean milk machine motor, Fan motor, air condition motor, fractional motor, direct current motor, AC brushless motor, water pump, transformer, rectifier, lighting, rechargeable battery,electric heating appliance etc.
