Üç / Tek Fazlı AC / DC Motor için Bimetal Aşırı Yük Termal Koruması

Hi-Amp motor bimetal aşırı yük termal koruma anahtarı motor devrelerine monte edilmiştir, ve motora giden akım bimetalik tetikleme elemanından geçer. 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. Sabah 17'nin en belirgin özelliği / KSD9700 / verem / 6AP/ 3MP/ 5AP serisi termal aşırı yük anahtarı / motor termal koruma anahtarı küçük hacimli ve büyük akım taşıma kapasitesidir.

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, Aşırı ısınma koruması, 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, trafo, rectifier, aydınlatma, rechargeable battery,electric heating appliance etc.
