Schneider Electric M9F42325 Three Phase Circuit Breaker

Schneider Electric M9F42325 is a three‑pole Miniature Circuit Breaker (MCB) from the Multi9 C60BP family, rated at 25 A with a C‑curve trip characteristic. Suited for 480Y/277 V AC three‑phase distribution, it provides a 10 kA breaking capacity under UL 489 and IEC/EN 60947‑2, delivering reliable protection against overload and short circuits for individual circuits in commercial and light industrial panels. The 3P, 25A M9F42325 is designed for modular installation in Schneider Electric’s distribution equipment, enabling straightforward replacement in compatible busbar systems and enclosures that accept Multi9 C60BP devices. With its thermal‑magnetic tripping mechanism, it responds to both overload currents and short‑circuit events, helping to minimize downtime and simplify feeder protection. This catalog number is part of Schneider Electric’s legacy M9F line, commonly used in control panels, switchboards, and energy distribution assemblies where a compact, standard‑form MCB is required for three‑phase protection at a 25‑amp rating.
