Ububanzi besicelo

♦ Ama-circuit breaker ochungechunge lwe-S7D anezinzuzo zokubukeka okuncane, isisindo esilula, imisebenzi emihle kakhulu futhi enokwethenjelwa, umthamo wokuphuka okuphezulu, ukukhubeka ngokushesha kanye nempilo ende.
♦Mayelana nokufakwa komhlahlandlela, ikesi nezingxenye, zisebenzisa amapulasitiki okumelana nomthelela omkhulu.
♦ Asetshenziswa kakhulu kusekethe ye-AC 50Hz/60Hz ene-volage yokusebenza elinganiselwe engu-415V noma ngaphansi kwamasekhethi ahlinzekiwe anokuvikela okugcwala kakhulu kanye nesekhethi emfishane, nokwenza nokuphula idivayisi kagesi kanye nesekethe yokukhanyisa ngendlela engafanele.
♦ Umkhiqizo ungafakwa ngokudedelwa kwe-undervoltage kanye nokukhululwa kwe-shunt, futhi ungase usetshenziselwe ukuhlukanisa, nokuvikela ukungahambi kahle kwesekhethi kanye nokuphula ibanga elide.
