Westinghouse MCGA3800F Ground Fault Circuit Breaker

Westinghouse MCGA3800F is a three‑pole molded‑case circuit breaker rated for 800 A and designed for industrial power distribution, delivering protection up to 600 V with built‑in ground‑fault protection to automatically interrupt a circuit when a fault to ground is detected. As part of the MCGA/MCG family, it shares a heavy‑duty MC frame suitable for large feeders and equipment in commercial or industrial panels. This 800 A, 600 V device is used to protect feeders feeding high‑load equipment such as large motors and compressors, offering reliable overload and ground‑fault protection for 3‑phase electrical systems. Key specifications include: 3‑pole configuration, 800 A nominal current rating, and 600 V maximum system voltage, with integration as a main or subfeed protective device in industrial distribution networks.
