Imodeli encane ye-AC contactor CJX2-K12 iyidivayisi kagesi evame ukusetshenziswa kumasistimu wamandla. Umsebenzi wayo wokuxhumana unokwethenjelwa, ubukhulu bayo buncane, futhi ifanele ukulawulwa nokuvikelwa kwamasekethe e-AC.
I-CJX2-K12 encane yokuxhumana ye-AC isebenzisa indlela enokwethenjelwa kagesi ukuze ibone ukulawula kokushintsha kwesekethe. Imvamisa iqukethe uhlelo lwe-electromagnetic, uhlelo lokuxhumana kanye nohlelo lokuxhumana olusizayo. Isistimu kazibuthe kagesi ikhiqiza amandla kazibuthe kagesi ngokulawula amandla akhona kukhoyili ukuze ihehe noma inqamule abathintwayo abakhulu bekhoyili. Uhlelo lokuxhumana luqukethe othintana nabo abakhulu kanye noxhumana nabo abasizayo, abanomthwalo omkhulu wokuthwala amasekhethi amanje kanye nokushintsha. Oxhumana nabo abasizayo bangasetshenziswa ukulawula amasekhethi asizayo njengamalambu ezinkomba noma ama-siren.
