Overview
The SRM-12/630A vacuum circuit breaker is a dedicated vacuum circuit breaker for 12KVSF6 gas charging cabinets. The switch adopts
a clamp type structure, which has the advantages of reliable breaking performance, long service life, maintenance free, and easy
installation. The SRM-12/630A vacuum circuit breaker is mainly used in the 12KV/630 SF6 gas filled cabinet. As the main component
of the gas filled cabinet, it undertakes the main function and has performance such as breaking and closing rated current, load
current making, and breaking short circuit current.
Environmental conditions for use
