Schneider Electric MA MA3800F Circuit Breaker

Schneider Electric Square D MA3800F is a three‑pole molded‑case circuit breaker in the MA series designed for 600 V AC systems. It carries an 800 A frame rating and a 500 A trip rating, enabling protection for high‑current feeders in industrial distribution panels. Cataloged as a complete MA3800F, this unit is compatible with 50/60 Hz operation up to 600 V and leverages a thermal‑magnetic trip mechanism to provide overload and short‑circuit protection in three‑phase circuits. The MA3800F designation sits within the Westinghouse/MA lineage that Schneider Electric’s Square D family continues to reference in distributor catalogs, offering a replacement option for legacy installations. When replacing this model, you should verify mounting style and terminal configuration to ensure proper fit with your panel or bus arrangement.
