Proteção térmica de sobrecarga bimetálica para motor CA/CC trifásico/monofásico

O interruptor de proteção térmica de sobrecarga bimetálica do motor Hi-Amp é instalado em circuitos de motor, e a corrente que vai para o motor passa pelo 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. A característica mais marcante das 17h / KSD9700 / TB / 6Interruptor de sobrecarga térmica série AP/3MP/5AP / o interruptor de proteção térmica do motor é de pequeno volume e grande capacidade de transporte de corrente.

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, lighting, rechargeable battery,electric heating appliance etc.
