The Schneider Electric C60H2P25AD is a C60H miniature circuit breaker from the Multi9 range, rated 25 A at 40 °C with a D tripping curve (magnetic trip 10–14 x In). It protects a single pole plus neutral (1P+N) and is suited for distribution boards where high inrush loads — motor starting, transformer energisation, discharge lighting — demand a delayed magnetic release to avoid nuisance trips. The 1P+N format means the neutral is switched and protected, not just a solid bar, which is required in some regional wiring rules and for isolation duty (the part carries IEC 60947-2 isolation suitability).
Breaking capacity varies with voltage: 30 kA Icu at 230–240 V AC, 15 kA at 400–415 V AC, and 10 kA at 440 V AC (all per IEC 60947-2). At 125 V DC (2-pole series connection) it reaches 25 kA Icu. For a 25 A MCB in a typical 230/400 V panel, the 15 kA at 400 V gives solid headroom above the usual 10 kA prospective short-circuit current in most commercial installations, meaning the breaker can clear a fault without upstream fuse backup in all but the highest-fault locations. The limitation class is 3 per IEC 60947-2, which limits let-through energy enough to protect downstream cables and equipment.
Width is 36 mm (4 x 9 mm pitches), depth 73 mm, height 81 mm — fits standard distribution board cutouts. The toggle handle gives clear ON/OFF indication and a contact position indicator confirms isolation status. Ambient operating range is –25 to 60 °C, storage –40 to 70 °C, with tropicalisation per IEC 60068-1 (2-class humidity resistance).
