The W3 2000H 2000A4P Fixed Horizontal Molded Case Circuit Breaker is a protection device engineered for AC230V power distribution systems, ideal for industrial/commercial grids, equipment control centers, and scenarios requiring stable power management. Its modular design integrates structural optimization and material innovation to deliver efficient circuit interruption and dependable performance.
At its core, the breaker incorporates a precision electromagnetic trip mechanism and thermal protection system, enabling rapid response to overloads and short circuits. The silver-alloy composite contacts, combined with a multi-layer arc-extinguishing chamber, enhance breaking capacity and electrical durability while maintaining stable conductivity. The flame-retardant housing, constructed from high-strength materials, ensures resistance to high temperatures and mechanical stress in challenging environments.
The fixed horizontal configuration simplifies installation within switchgear cabinets, supporting both rail mounting and bolt fixing for secure connections under vibration conditions. The front panel features intuitive status indicators and a manual operating handle, allowing quick identification and control of breaker status. The exclusion of undervoltage release prioritizes fundamental circuit protection, minimizing unintended tripping caused by voltage fluctuations.
This model is widely deployed in data centers, production lines, and commercial buildings for main circuit protection. It supports copper busbar and cable connections, adapting to diverse power distribution layouts. Rigorous factory testing guarantees consistent performance under rated loads. The compact design optimizes space utilization and heat dissipation, reducing deployment complexity in integrated power systems.
