Schneider Electric C125N360FM ComPacT NS1250N 3P 1250 A 50 kA MicroLogic 6.0 Moulded Case Circuit Breaker

The Schneider Electric C125N360FM is a 3-pole, 1250 A ComPacT NS1250N moulded case circuit breaker rated for 50 kA breaking capacity (Icu) at 380/415 V AC. Fixed-mounted and manually operated, it carries a MicroLogic 6.0 electronic trip unit delivering long-time overload, short-time delay, instantaneous and ground-fault protection, and is rated up to 690 V AC for standard-breaking-capacity distribution duty in the ComPacT NS630b...1600 new generation line.

Selection Notes

The N-frame classification gives the C125N360FM 50 kA Icu at 380/415 V AC, sized for standard distribution duty on the 1250 A frame; where fault levels run higher, the H-frame version of the same frame size delivers a higher Icu without a change in footprint. Its MicroLogic 6.0 trip unit adds ground-fault protection on top of the short-time delay stage carried by the 5.0 (LSI) units in this frame, giving long-time, short-time, instantaneous and ground-fault discrimination (LSIG) in one device. The base MicroLogic 6.0 unit has no digital display — settings are read off the dial markings, with no RMS or energy readout. At 210 mm wide on 3 poles, it suits 3-phase-only distribution with no neutral protection; the 4-pole version of the same frame is available where the neutral conductor must be switched and protected.
