The WCW1 Series 2000A Intelligent Universal Air Circuit Breaker from Westhomes is a cutting-edge solution for AC 50Hz distribution networks, with rated voltage options of 400V and up to 690V.
Whether you’re managing complex energy distribution or seeking to upgrade your system with smart protection technology, the Westhomes WCW1 2000A Universal ACB offers the reliability, intelligence, and scalability your operations demand.
With a robust rated current of 2000A, this advanced ACB (Air Circuit Breaker) delivers high-capacity performance for industrial, commercial, and infrastructure-grade power systems.
Built for reliable power distribution and fault protection, The WCW1 Series 2000A Intelligent Universal Air Circuit Breaker safeguards critical equipment against overload, Undervoltage, short circuit, and single-phase grounding faults. Its intelligent protection system ensures precise fault detection and rapid response, improving the stability and continuity of power supply while minimizing unnecessary interruptions.
Key features include an open communication interface that enables Four Remote Functions: remote control, remote monitoring, remote signalling, and remote setting. These features support seamless integration with SCADA systems, smart grid frameworks, and advanced energy automation platforms.
Engineered for high-stress environments, the WCW1 ACB delivers impulse withstand voltage of 8000V at 2000 meters altitude, with design standards supporting operation up to 12000V at higher altitudes. Its universal application flexibility, combined with global voltage compatibility (400V / 690V), makes it a preferred choice for large-scale industrial facilities, data centres, substations, and commercial power systems.
