Description:
ZW32 vacuum circuit breaker is applied outdoors and is generally installed at the upper end of the transformer. It belongs to the pillar type and is commonly installed on outdoor utility poles. There are also floor standing installations with enclosures, also known as column switches. Because it can cut off the circuit, it is the boundary point between high and low voltage at the upper end of the transformer, also known as the boundary switch. It has overcurrent and phase loss zero sequence protection, and plays a role in switching circuits and protecting loads such as transformers.

Applications:
The ZW32 Outdoor Vacuum Circuit Breaker is widely applied in:
Overhead medium-voltage distribution lines
Pole-mounted distribution systems
Outdoor substations and feeder protection points
Industrial power distribution networks
Renewable energy grid connection systems
Its design supports continuous outdoor operation while maintaining consistent switching performance and system protection.

When there is overcurrent or short circuit in the outgoing line of the circuit, the current transformer can detect the current signal, which is transmitted to the controller. The controller issues a command to trip the mechanism, which drives the dynamic and static contacts inside the vacuum tube to separate, thereby achieving disconnection and cutting off the circuit, playing a protective role.Â
To ensure transportation safety, our electrical products are exported in reinforced wooden crates. The crates undergo heat treatment and bear the ISPM-15 mark, enabling swift customs clearance. The raised base design facilitates forklift operation, while internal shock-absorbing fastening ensures the products arrive intact. All exterior crates are clearly labeled and comply with international logistics standards.
