Scope ntawm daim ntawv thov

♦S7D series circuit breakers muaj qhov zoo ntawm qhov me me, lub teeb yuag, zoo heev thiab txhim khu kev qha, muaj peev xwm tawg ntau dua, tripping sai thiab lub neej ntev.
♦Raws li qhov kev teeb tsa qhia, lub thawv thiab cov khoom seem, lawv siv cov yas uas tiv taus thiab cuam tshuam tau zoo.
♦Lawv feem ntau yog siv rau AC 50Hz / 60Hz Circuit nrog qhov ntsuas hluav taws xob 415V lossis tsawg dua muab cov circuits nrog kev tiv thaiv overload thiab luv luv, thiab ua thiab tawg cov khoom siv hluav taws xob thiab lub teeb pom kev zoo feem ntau.
♦Cov khoom no muaj peev xwm ntsia tau nrog kev tso tawm qis zog thiab kev tso tawm shunt, thiab kuj siv tau rau kev sib cais, thiab tiv thaiv qhov tsis muaj zog ntawm lub voj voog thiab rhuav tshem qhov deb ntev.
