WCW1 Series Intelligent Circuit Breaker | 3200A 3P | Smart Protection
WCW1 High-Speed Circuit Breaker is widely used in industrial plants, data centres, infrastructure projects, and smart energy distribution networks, where safety, precision, and communication compatibility are critical.
Engineered for advanced power distribution and protection, this WCW1 High-Speed Circuit Breaker safeguards electrical lines and power equipment against faults including overload, Undervoltage, short circuit, and single-phase ground faults.
Featuring intelligent protection capabilities, the WCW1 circuit breaker ensures accurate fault identification and selective tripping, enhancing the reliability of the power supply and minimizing unnecessary power outages. Its open communication interface supports “Four Remote Functions”—remote control, remote measurement, remote communication, and remote adjustment—making it ideal for integration into modern SCADA systems and smart grids.
Built to withstand harsh environments, this circuit breaker provides an impulse withstand voltage of up to 8000V at 2000 meters altitude. It complies with altitude-specific standards and is tested to ensure safe operation even at high elevations (up to 12000V impulse withstand according to applicable standards).
