12kV Outdoor Pole-Mounted Vacuum Circuit Breaker ZW20
The ZW20 outdoor intelligent pole-mounted vacuum circuit breaker has a rated voltage of 12kV. It uses a three-phase common-enclosure sealed enclosure with an internal vacuum interrupter for breaking the circuit. The enclosure is insulated with SF6 gas. The circuit breaker can be configured with an FTU intelligent controller (watchdog) for remote control. It integrates current transformers and zero-sequence transformers to achieve line protection, fault detection, fault isolation, automatic reclosing, and three-remote communication, meeting the needs of intelligent distribution network automation. Multiple current schemes are available.
