specifications
technical

zw32-40.5/1600-25 outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker is mainly composed of integrated solid-sealed pole, current transformer, operating mechanism and cabinet. an isolating switch can be installed. this type of circuit breaker has a miniaturized design, and the shell is made of high-quality steel box. the current transformer can be selected according to user needs.

the device is mainly used in medium-voltage overhead line power grids for dividing and combining load current, overload current and short-circuit current.

ambient air temperature: -30°c ~ 60°c;

altitude:≤ 3000 meters;

the wind speed:≤ 34m/s;

vibration or ground movement from the outside of the switchgear cell system can be ignored;

pollution level: level iv;

storage temperature -40°c ~ 85°c.
