ZW7-40.5

OUTDOOR HIGH VOLTAGE INTELLIGENT
VACUUM CIRCUIT BREAKER

Overview
ZW7-40.5F (M) outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker uses a uniquely designed split pole and high reliability
spring operating mechanism or permanent magnet operating mechanism. The device is mainly used in medium-voltage overhead line power grids as a
branching and closing load current, overload current, and short-circuit current.
