ZW32-12F(G)/ZW32M-12 Outdoor Intelligent (Electronic Watchdog) / Permanent-Magnet Type High-Voltage Vacuum Circuit Breaker
The ZW32-12F(G)/ZW32M-12 series-comprising outdoor intelligent (with electronic "watchdog" functionality) and permanent-magnet type high-voltage vacuum circuit breakers-are designed for three-phase AC 50Hz power systems with a rated voltage of 12kV. These intelligent circuit breakers are primarily used as 10kV outgoing feeders in substations or as line protection switches within 10kV three-phase AC power systems, capable of making and breaking load currents, as well as interrupting overload and short-circuit currents. They fulfill requirements for control, measurement, and metering, while also supporting remote control and monitoring-enabling "four remote" functions (remote control, remote signaling, remote measurement, and remote adjustment).
These circuit breakers comply with technical standards including GB 1984 "High-voltage AC Circuit Breakers," DL/T 402 "Technical Specifications for Ordering High-voltage AC Circuit Breakers," and DL/T 403 "Technical Specifications for Ordering 12kV–40.5kV High-voltage Vacuum Circuit Breakers."
