Kolme-/ühefaasilise vahelduv-/alalisvoolumootori bimetallist ülekoormuskaitse

Hi-Amp mootori bimetallist ülekoormuse termokaitselüliti on paigaldatud mootoriahelatesse, ja mootorisse minev vool läbib bimetallist väljalülituselementi. 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. Kella 17 kõige silmapaistvam tunnusjoon / KSD9700 / TB / 6AP/3MP/5AP seeria termilise ülekoormuse lüliti / mootori termokaitselüliti on väikese mahu ja suure voolu kandevõimega.

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, trafo, rectifier, valgustus, rechargeable battery,electric heating appliance etc.
