Structure characteristic

The mini circuit breaker uses high accuracy bimetal for inverse time lag. Thermal protection element, accurate protection characteristic. The contact system adopt double breakpoints serial link structure,double arc extinguish system, low voltage of breakpoint, good characteristic of current limiting at a high breaking capacity. have obvious position state Indication ; connectin g terminal adopt enhance type frame construction, can connect to lead of 2.5mm²~50mm².

The circuit breake r can be with shunt release,auxiliary contact etc accessories.
