Chishandiso chekupisa chine simba rekudzivirira kupisa chakagadzirwa nemhangura chinoshandiswa zvakanyanya mukudzikisa magetsi emagetsi ane simba remagetsi, thermal overload relay, nezvimwe zvigadzirwa zvemagetsi zvine simba remagetsi. Ndicho chimwe chezvinhu zvakakosha zvezvigadzirwa zvemagetsi zvine simba remagetsi. Zvinhu zvakagadzirwa nekambani yedu zvine hunhu hwekudzivirira kwakanaka uye kugadzikana kwakanyanya. Tinogona kupa marudzi ese ewaya dzakatenderera, dzakatsetseka uye dzakapfava.

CuNi2 kuramba kwakadereraChishandiso chekupisa chinoshandiswa zvakanyanya mu low-voltage circuit breaker, thermal overload relay, nezvimwe zvigadzirwa zvemagetsi zvine low-voltage. Ndiyo imwe yezvinhu zvakakosha zvezvigadzirwa zvemagetsi zvine low-voltage. Zvinhu zvinogadzirwa nekambani yedu zvine hunhu hwe resistance yakanaka uye kugadzikana kwakanyanya. Tinogona kupa marudzi ese ewaya dzakatenderera, dzakatsetseka uye dzakatetepa.

Chiumbwa ichi hachina magineti. Chinoshandiswa pakugadzirisa simba remagetsi rinochinja-chinja uye pakugadzirisa simba,
potentiometers, waya dzinodziya, tambo dzinodziya nemateti. Ribhoni dzinoshandiswa pakudziisa bimetals. Imwe nzvimbo inoshandiswa kugadzira thermocouples nekuti inovandudza simba remagetsi (EMF) pamwe chete nedzimwe simbi.
