三/單相AC/DC電動機嘅雙金屬過載熱保護

Hi-Amp電機雙金屬片過載熱保護開關安裝在電機電路中, 流向電機嘅電流通過雙金屬脫扣元件. 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. 17AM最顯著嘅特點 / KSD9700 / 結核病 / 6AP/ 3MP/ 5AP系列熱過載掣 / 電機熱保護開關體積小，載流能力大.

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, 火牛, rectifier, 照明, rechargeable battery,electric heating appliance etc.
