The Schneider Electric C60H2P25AC is a 1P+N miniature circuit breaker from the Multi9 C60H range, rated 25 A at 30 °C with a C trip curve (magnetic tripping between 5 and 10 times In). It breaks up to 10 kA Icu at 440 V AC (IEC 60947-2), which is the figure that governs its fault-clearing ability in a 400 V three-phase distribution board; at 230 V it handles 30 kA, so it's comfortable in a main sub-feed position as long as the upstream device limits let-through energy below that. The 1P+N configuration switches the phase and switches the neutral but does not protect the neutral — only the phase pole is protected. It occupies 4 module pitches (36 mm width) on a 35 mm symmetrical DIN rail, so it's a straightforward swap into any Multi9 or similar DIN-rail distribution board.
The neutral position is left, which matters when you're laying out busbars or pre-wired neutral links in a distribution board — keep the neutral bar on the left side of the MCB. The toggle gives local ON/OFF indication, and there's a contact position indicator so you can visually confirm the state without relying on the handle position alone. That's a nice safety check for a junior tech doing a panel walk-down. Depth is 73 mm, height 81 mm. That's a standard Multi9 footprint — fits existing enclosures without a gland-plate or cover-depth surprise. Tropicalisation per IEC 60068-1 means it's tested for damp heat, so it's fine in non-conditioned electrical rooms.
