Protección térmica de sobrecarga bimetálica para motor trifásico/monofásico AC/DC

El interruptor de protección térmica de sobrecarga bimetálica del motor de alto amperaje está instalado en los circuitos del motor., y la corriente que va al motor pasa a través del elemento de disparo bimetálico. The flowing current heats the bimetallic strip which causes the bimetallic material to bend, and after a specific temperature, the bimetallic strip will open the thermal protection switch. La característica más destacada de las 17 a.m. / KSD9700 / tuberculosis / 6Interruptor de sobrecarga térmica serie AP/ 3MP/ 5AP / El interruptor de protección térmica del motor tiene un volumen pequeño y una gran capacidad de carga de corriente..

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, transformador, rectifier, iluminación, rechargeable battery,electric heating appliance etc.
