Sebenzisa ubuchwepheshe bokutshintsha i-synchronous zero – crossing switch. I-circuit breaker contact dynamic and static phantsi kolawulo lwenkqubo yolawulo lwe-elektroniki, ingaba i-system voltage waveform kwinqanaba ngalinye, kwi-current waveform ukuya kwi-zero xa ikhefu, i-inrush current kunye ne-over voltage amplitude incinci, ukunciphisa impembelelo kwigridi kunye nokusebenza kwezixhobo, kwaye indlela yokusebenza ye-electromagnetic kunye nokusebenza kwendlela yokusebenza yentwasahlobo ayicwangciswanga, inokuvelisa i-inrush current ephezulu kunye ne-over voltage amplitude, Impembelelo enkulu kwiigridi zamandla kunye nezixhobo.

Indlela yokusebenza yemagnethi esisigxina inokuphumeza ukusebenza kwendawo/ekude kokuvula nokuvala, inokwenza nomsebenzi wokukhusela nokuvala, ingavulwa ngesandla. Ngenxa yokuba ukusebenza kwamandla afunekayo kuncinci, ukusetyenziswa kwee-capacitors kumbane otshintsha ngqo, ixesha lokutshaja kwe-capacitor lifutshane, umsinga wokutshaja uncinci, ukumelana okunamandla kwempembelelo, emva kokucinywa kombane kusenokubakho kwi-circuit breaker.

Iingxaki eziphambili zendlela yokusebenza kwemagnethi esisigxina zezi:

Ayikwazi ukuvala ngesandla, xa umbane uphela, amandla e-capacitor aphelile, ukuba i-capacitor ayinakutshajwa, ayinakuvalwa;

Ukuvula ngesandla, isantya sokuqala sokuvula kufuneka sibe sikhulu ngokwaneleyo, ngoko ke kufuneka amandla amaninzi, kungenjalo ayinakusetyenziswa;

Umgangatho wee-capacitor zokugcina amandla awulingani kwaye kunzima ukuwuqinisekisa;

Kunzima ukufumana uphawu olufanelekileyo lwesantya sokuvula;

Kunzima ukwandisa amandla okuvula amandla okusebenza kwemagnethi esisigxina.
