The C100N460FM is a Schneider Electric ComPacT NS new generation 4-pole fixed circuit breaker, rated 1000 A at 50 °C, with a MicroLogic 6.0 electronic trip unit providing L (long-time overload), S (short-time short-circuit), I (instantaneous), and G (ground-fault) protection. The 85 kA Icu at 240 V AC and 50 kA at 415 V AC mean this breaker can safely interrupt fault currents up to those levels without upstream coordination failure; the N breaking capacity code (50 kA at 415 V) tells you it's rated for high-fault industrial networks. The 1000 A frame and trip unit are matched, so you don't need to oversize the breaker for the load — it's already sized for a 1000 A feeder or main.
Trip unit and protection logic
MicroLogic 6.0 is an electronic trip unit with a 20-minute thermal memory. That memory means the breaker remembers prior heating from overloads and shortens the trip time on a repeated event — important for motor or transformer feeders where inrush can mask a developing fault. The L, S, I, G protection curves are adjustable via the trip unit's dials, giving you selectivity coordination downstream. No integral earth-leakage protection is included; if you need that, you add an external Vigi module.
Fixed mounting on a backplate, with front connections both upside and downside. Neutral is on the left. Dimensions: 280 mm wide, 327 mm high, 147 mm deep. IK07 impact rating handles accidental tool strikes during installation.
Local signalling and diagnostics
Four red LEDs for fault indication (trip cause) and one yellow LED for overload pre-alarm. That saves time on troubleshooting — you can read the trip history without plugging in a laptop. The manually operated control type means no motor operator is built in; add one externally if remote switching is needed.
