Description
About the C080N42EFM
About the C080N42EFM
The Schneider Electric C080N42EFM is a 4-pole ComPacT NS800N moulded case circuit breaker rated 800 A, with a 50 kA breaking capacity (Icu) at 380/415 V AC. It is fitted with a MicroLogic 2.0 E trip unit delivering long-time overload and instantaneous short-circuit protection (LI), is fixed-mounted and manually operated, and carries a 690 V rated operational voltage for industrial distribution switchboards.

- EN/IEC 60947-2
Selection Notes
Its LI trip unit covers long-time overload and instantaneous short-circuit tripping only, which keeps the breaker simple and is adequate where upstream or downstream devices already handle short-time discrimination. The energy-meter display adds load energy tracking on top of the RMS current reading, useful for sub-metering a feeder. The N-frame rating gives it 50 kA Icu at 380/415 V AC, the standard distribution class for this amperage; step up to an H-frame sibling at the same 800 A when the prospective fault current at the installation point exceeds this breaker's Icu. The 4-pole version adds a switched or protected neutral, which is the variant to specify on a TT or IT system where the neutral itself needs disconnection or protection.
