Product Description

ZW32-40.5F(M) High-Speed Outdoor Pole Mounted Overhead
Vacuum MCB Circuit Breaker

Product Description

Overview
ZW32-40.5 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's 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.

Using conditions
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.
