The Schneider Electric C60H2P1AC is a 1P+N miniature circuit breaker from the Multi9 C60 range, rated 1 A with a C curve (magnetic trip at 5–10 x In). The 1 A rating protects a low-current branch; at 30 °C ambient it carries 1 A continuously, and the thermal-magnetic trip handles both overload and short-circuit conditions. Breaking capacity is 10 kA Icu at 440 V AC per IEC 60947-2, with higher ratings at lower voltages: 15 kA at 400–415 V AC, 30 kA at 230–240 V AC. For a 1 A MCB on a typical 230/400 V distribution board, the 10 kA at 440 V is the limiting figure — it confirms the breaker can safely interrupt a fault up to that level without welding contacts or cascading upstream. The 25 kA DC rating at 125 V DC (2P series-connected) is available if the same frame is used in a DC sub-panel. The 1P+N configuration protects the phase only; the neutral pole is switched but not protected. That's standard for single-phase final circuits where the neutral is solidly bonded at the distribution board. The neutral position is left, matching the typical busbar arrangement in Schneider distribution boards.
At 4 module pitches (36 mm wide per module, so 144 mm total), it occupies four 18 mm slots in a standard distribution board. Depth is 73 mm, height 81 mm — check enclosure fill factor if the board is tight, but the footprint is standard for a 1P+N MCB in the Multi9 family. The contact position indicator and ON/OFF local signalling give a quick visual check during commissioning or troubleshooting.
