Биметална термична защита от претоварване за три/еднофазен AC/DC двигател

Hi-Amp биметален превключвател за термична защита от претоварване на двигателя е инсталиран във веригите на двигателя, и токът, който отива към двигателя, преминава през биметалния изключващ елемент. 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. Най-забележителната характеристика на 17 сутринта / KSD9700 / туберкулоза / 6Превключвател за термично претоварване от серия AP/ 3MP/ 5AP / превключвателят за термична защита на двигателя е малък обем и голям капацитет на ток.

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, трансформатор, rectifier, осветление, rechargeable battery,electric heating appliance etc.
