Product details

MCCB for distribution — 1000 A, MicroLogic 2.0 A, 4P

The Schneider Electric C100H42AFM is a ComPacT NS new generation moulded-case circuit breaker rated 1000 A at 50 °C, with a MicroLogic 2.0 A electronic trip unit providing L (long-time overload) and I (instantaneous short-circuit) protection. The 4-pole, fixed-mount format with front connections suits backplate installation in switchboards where space is planned around a 280 mm width and 327 mm height.

Rated 85 kA Icu at 240 V AC, 70 kA at 415 V, 65 kA at 440 V, 50 kA at 500 V, and 42 kA at 690 V — all per IEC 60947-2. The H breaking capacity code (70 kA at 415 V) means this breaker coordinates well downstream of a higher-rated upstream device, keeping fault energy contained.

Fixed mount on a backplate, 70 mm connection pitch, front upside and downside connections. The 4-pole format with neutral on the left matches standard panel layout practice.
