C125N360FM Schneider Electric – ComPacT NS1250N Circuit Breaker, 1250 A, 50 kA, 3P, MicroLogic 6.0 (LSIG), Fixed, Manually Operated
The Schneider Electric C125N360FM is a new-generation ComPacT NS1250N circuit breaker for main and sub-main low-voltage distribution. It is a fixed, manually operated 3-pole breaker rated 1250 A with a breaking capacity of 50 kA at 415 V. It is fitted with the MicroLogic 6.0 electronic control unit, which provides full LSIG protection: long-time, short-time, instantaneous and ground-fault. It replaces the previous-generation Compact NS1250N MicroLogic 6.0 3P fixed (former reference 33919). The new version adds a transparent front cover so the auxiliaries are visible.
