Chikamu chekushandisa

♦S7D akateedzana masekete mabreaker ane zvakanakira kutaridzika kudiki, huremu huremu, akanakisa uye akavimbika mabasa, yakakwirira yekutyora kugona, kukurumidza kugumburwa uye hupenyu hwakareba.
♦ Kana iri yekumisikidzwa kwegwaro, kesi uye zvikamu, vanotora kupikisa kwakanyanya uye kukanganisa kupikisa mapurasitiki.
♦ Iwo anonyanya kushandiswa kune AC 50Hz/60Hz dunhu rine rated operation volage 415V kana mashoma kupa maseketi ane overload uye pfupi-circuit dziviriro, uye kugadzira uye kutyora mudziyo wemagetsi uye mwenje wedunhu zvisingaite.
♦ Chigadzirwa chacho chinogona kuiswa ne undervoltage release uye shunt release, uye zvakare inogona kushandiswa kuparadzanisa, nekudzivirira undervoltage yedunhu uye kuputsa kureba.
