DZ47-63DZ47-100-Circuit Breaker Series-China · Huabang Power Technology Co., Ltd.

summary:

DZ47-63/DZ47-100 high breaking miniature circuit breaker (air switch) is suitable for protecting short circuits and overloads of power lines, and is suitable for lighting distribution systems or motor distribution systems. It has a beautiful and compact appearance, light weight, excellent performance, high reliable breaking capacity, quick tripping, rail installation, and the shell and components are made of high flame retardant and impact resistant plastic. It has a long service life and is mainly used for overload and short circuit protection of AC 50Hz, rated voltage up to 400V, and rated current up to 63A lines. At the same time, it can also frequently turn on and off electrical devices and lighting lines under normal circumstances. This product complies with the GB10963.1 standard.
