Product details

The Schneider Electric C125N360FM is a 3-pole ComPacT NS new generation circuit breaker rated 1250 A at 50 °C, with a MicroLogic 6.0 electronic trip unit. This is a distribution breaker, not a motor-protection device — the LSI protection curve (long-time, short-time, instantaneous) is set for feeder or main switchboard duty. The MicroLogic 6.0 trip unit provides electronic overload (L), short-time short-circuit (S), and instantaneous (I) protection, with a 20-minute thermal memory that prevents nuisance reclosing after a thermal trip. Earth-leakage protection is not integrated — specify an external Vigi module if ground-fault detection is needed.

Physical integration and environment

Fixed-mount, backplate installation. Dimensions: 327 mm high, 210 mm wide, 147 mm deep. Connection pitch is 70 mm; both upside and downside connections are front-accessible. Power losses are 44 W at rated current — factor that into panel thermal calculations.

Frequently asked questions

What is C125N360FM's breaking capacity at 415 V?

50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. That is the N breaking capacity code — suitable for most industrial distribution panels with a 415 V supply.

What protection curves does the MicroLogic 6.0 trip unit provide?

LSI: long-time overload (L), short-time short-circuit (S), and instantaneous (I). No ground-fault (G) protection is built in — add an external Vigi module if needed.
