The C60H1P63AC is a 1-pole miniature circuit breaker from the Multi9 C60H series, rated 63 A at 30 °C with a C-curve trip characteristic (magnetic tripping between 5 and 10 times In). That C curve means it handles moderate inrush — typical for motor starters, lighting banks, and transformer primaries — without nuisance trips, while still clearing short circuits fast enough for most distribution panels. The 15 kA Icu at 230…240 V AC (IEC 60947-2) is the maximum fault current it can safely interrupt; the Ics rating of 7.5 kA at the same voltage tells you it can reclose after a fault at that level without immediate replacement. For 400…415 V AC networks, the Icu drops to 4 kA and the Ics to 2 kA — so on a 400 V three-phase panel, this breaker needs upstream coordination to stay within those limits. That terminal capacity is generous for a 63 A breaker — it lets you land the full-rated conductor without pigtailing or splicing.
Deployment context
It is certified to both IEC 60947-2 (industrial) and EN 60898 (residential/commercial) — so it qualifies for either duty, but the lower Ics at 400 V means it is best applied as a downstream branch breaker, not a main. Rated operational voltage spans 12…440 V AC 50/60 Hz, with a 500 V insulation voltage and 6 kV impulse withstand.
