The Westhomes WCW1 Series 2000A 3P Intelligent Air Circuit Breaker is a high-capacity protection device for AC 50Hz power distribution systems. Rated up to 690V and 2000A, it provides overload, short circuit, undervoltage, and single-phase ground fault protection in industrial, commercial, and infrastructure-grade applications.
Deployed in industrial automation, data centers, power substations, and renewable energy grids, the WCW1 2000A 3P ACB delivers reliable protection with global voltage compatibility at 400V and 690V for high-demand applications.
With a rated voltage up to 600V (maximum 690V) and a rated current of 2000A, this three-pole (3P) air circuit breaker delivers consistent performance in industrial, commercial, and infrastructure-grade power networks.
Built to distribute power and protect electrical systems, the WCW1 2000A 3P ACB covers overload, undervoltage, short circuit, and single-phase ground fault protection. Its microprocessor trip unit delivers precise fault detection and selective tripping, maintaining operational continuity and reducing the risk of power interruptions.
The breaker supports four remote functions through its open communication interface: remote control, remote measurement, remote communication, and remote adjustment. These capabilities are suited for integration into SCADA systems, automated switchgear, and energy management platforms.
Tested for demanding environments, the WCW1 has an impulse withstand voltage of 8000V at 2000 meters altitude and complies with altitude-specific standards up to 12000V for stable operation at varying elevations.
