Cov ntawv thov

SF SX SA Hydraulic magnetic mini circuit breaker feem ntau yog siv rau oV erload thiab luv luv circuit tiv thaiv. Nws siv hydraulic magnetic trip es tsis yog bimetal. Yog li nws muaj kev rhiab heev. Thiab nws kuj tsis raug cuam tshuam los ntawm qhov kub thiab txias. Nws yog tshwj xeeb tshaj yog siv rau kev teeb pom kev zoo thiab kev faib tawm hauv kev lag luam thiab kev lag luam. Lawv feem ntau siv rau kev tiv thaiv overload thiab luv luv circuit hauv lub voj voog ntawm AC 50Hz / 60Hz, rated voltage ntawm ib tug ncej lossis ob tug ncej txog li 240V, peb tug ncej txog li 415V. lawv kuj tuaj yeem siv rau kev hloov pauv tsis tu ncua ntawm lub voj voog thiab teeb pom kev zoo nyob rau hauv cov xwm txheej ib txwm muaj.

Lawv ua raws li IEC157-1973, BC4752-1977 thiab BS3871 ntu 1.
