The electronic trip gives you adjustable short-time and instantaneous protection curves, which matters when you're coordinating downstream starters or VFDs and need to ride through inrush without nuisance trips. ## Breaking capacity across your voltage levels The Icu (ultimate breaking capacity) varies with system voltage, which is typical for MCCBs. At 240 V AC it's rated 85 kA, at 415 V it's 50 kA, at 440 V it's 42 kA, at 500 V it's 30 kA, at 525 V it's 22 kA, and at 690 V it holds 10 kA. That means in a 480 V panel (common in North American plants) you're looking at roughly 50 kA SCCR headroom if the assembly is listed to UL 60947-4-1. For European 400 V networks, the 50 kA figure covers most transformer-fed buswork. The breaker measures 255 mm high by 140 mm wide by 110 mm deep, mounts flat on a backplate in either horizontal or vertical orientation. Front connections top and bottom — no rear-access bus required, which simplifies gland-plate layout in a standard enclosure. Six accessory slots on the front for shunt trips, aux contacts, or alarms — enough for a full complement of status feedback to a PLC. ## Durability and thermal handling Mechanical endurance is 15,000 cycles; electrical endurance at full rated current (440 V In) is 4,000 cycles, and at half current it doubles to 8,000 cycles. That's typical for a 500 A frame — plenty for a motor centre where the breaker cycles maybe a few hundred times a year. Power dissipation is 25 W per pole, so 75 W total for the 3-pole unit at full load. That heat needs to be vented or factored into the enclosure's thermal budget; don't stack it tight against other high-dissipation gear without a derating check.","metaTitle":"Schneider Electric C63N31M500 ComPacT NSX630N Circuit Breake","metaDescription":"Schneider Electric C63N31M500 ComPacT NSX630N 3-pole circuit breaker with MicroLogic 1.3 M electronic trip unit.
