Schneider Electric C063N42AFM ComPacT NS630bN 4P 630 A 50 kA MicroLogic 2.0 A Moulded Case Circuit Breaker

The Schneider Electric C063N42AFM is a 4-pole ComPacT NS630bN moulded case circuit breaker rated 630 A, with a 50 kA breaking capacity (Icu) at 380/415 V AC. It is fitted with a MicroLogic 2.0 A 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.

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 devices already provide short-time discrimination. Step up to a 5.0-series LSI unit on a sibling variant when the installation needs an adjustable short-time delay for selective coordination with downstream breakers. The N-frame rating gives it 50 kA Icu at 380/415 V AC; within the NS630bN line this is the breaking-capacity class to pick when the calculated prospective short-circuit current at the installation point is at or below that figure without derating to a higher class.
