Perlindungan Termal Kelebihan Beban Bimetal untuk Motor AC/DC Tiga/Fasa Tunggal

Sakelar perlindungan termal kelebihan beban bimetal motor Hi-Amp dipasang di sirkuit motor, dan arus yang mengalir ke motor melewati elemen tripping bimetalik. 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. Fitur paling menonjol dari jam 17 pagi / KSD9700 / TBC / 6Sakelar beban berlebih termal seri AP/ 3MP/ 5AP / saklar perlindungan termal motor adalah volume kecil dan daya dukung arus besar.

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, transformator, rectifier, lighting, rechargeable battery,electric heating appliance etc.
