ZW32 Outdoor Vacuum Circuit Breaker

The ZW32 Outdoor Vacuum Circuit Breaker undergoes full commissioning and sealing at Ceho factory. A cable connector assembly for switch interconnection wiring is included. Accessories such as junction boxes or electronic switch control units are available as options. It boasts extremely high reliability; requires no maintenance throughout its entire service life; has a long mechanical and electrical lifespan; and is small in size, lightweight, and easy to install.

● Control voltage : 220V DC, inner self-supply from capacitor 250V, 22000 Uf. The end user only need to prepare relay main contacts for closing and opening.

● Auxiliary voltage: 110V/220V DC, 110V/220V AC optional by clients specify before the order

● Opening time: ≤ 8ms (Each switch will along with ex-work test record)

● Closing time: ≤ 11ms(Each switch will along with ex-work test record)

● Recommended control pulse time: 0.1s

Technical Parameter

ZW32 Auto recloser Structure

Three-phase pillar structure: Stable breaking performance, no risk of combustion or explosion, maintenance-free.

Fully enclosed structure: Excellent sealing, moisture-proof and condensation-proof, suitable for extremely cold or humid regions.

Insulation material: Uses silicone rubber or epoxy resin solid insulation, resistant to high and low temperatures, UV radiation, and aging.

Operating mechanism: Miniaturized spring mechanism or permanent magnet mechanism, fewer parts, high reliability, and low energy consumption.

Can be equipped with current transformers: Supports two-phase or three-phase CTs, with overcurrent protection and intelligent control functions.

Can be equipped with disconnecting switches: Creates a clear disconnection point, has anti-misoperation interlocking function, and facilitates maintenance.
