The Westhomes WCW1 Series 2000A 3P Intelligent Air Circuit Breaker is a high-capacity, smart protection device designed for modern AC 50Hz power distribution systems.
Whether deployed in industrial automation, data centres, power substations, or renewable energy grids, the WCW1 2000A 3P ACB provides the reliability, intelligence, and global voltage compatibility (400V/690V) necessary for high-demand applications.
With a rated voltage of up to 600V (maximum 690V) and a rated current of 2000A, this three-pole (3P) air circuit breaker offers dependable performance in industrial, commercial, and infrastructure-grade power networks.
Engineered to distribute power efficiently and protect electrical systems, the WCW1 2000A 3P ACB provides full-spectrum protection against overload, Undervoltage, short circuit, and single-phase grounding. Its intelligent protection system ensures precise fault detection and selective tripping, thereby enhancing operational continuity and reducing the risk of unnecessary power interruptions.
This air circuit breaker supports Four Remote Functions through its open communication interface—including remote control, remote measurement, remote communication, and remote adjustment—making it ideal for integration into SCADA systems, intelligent switchgear, and automated energy management platforms.
Tested for resilience in demanding environments, the WCW1 delivers an impulse withstand voltage of 8000V at 2000 meters altitude, and is compliant with altitude-specific standards up to 12000V, ensuring safe and stable performance at varying elevations.
