APPLICATION
high breaking miniature circuit breaker is used in lighting and motor protection system with protections of short circuit and over load. It mainly has the features of elegant and small, weight light, performance good and reliable, breaking capacity high, trip quickly, DIN installation and the material of shell and parts is high flameproof and anti-impact plastic ,life long. It is mainly applied in the system of 50/60Hz,single pole 230V,2,3,4poles for 400V as over load ,short circuit protection. And under voltage release, shunt release etc. And it also can be used in the isolation switch as the under voltage protection and remote distance breaking.
It conforms to IEC60947-2,GB14048.2
