Schneider Electric C063H460FM ComPacT NS630bH 4P 630 A 70 kA MicroLogic 6.0 Fixed Moulded Case Circuit Breaker

The Schneider Electric C063H460FM is a 4-pole ComPacT NS630bH moulded case circuit breaker rated 630 A, with a 70 kA breaking capacity (Icu) at 380/415 V AC. It is fitted with a MicroLogic 6.0 trip unit delivering long-time overload, short-time delay, instantaneous and ground-fault protection (LSIG), is fixed-mounted and manually operated, and carries a 690 V rated operational voltage for industrial distribution switchboards.

Selection Notes

Its LSIG trip unit adds adjustable ground-fault protection (Ig/tg) to the long-time, short-time and instantaneous functions, which this C063H460FM needs on a solidly-earthed or resistance-earthed system where a dedicated residual/ground-fault trip is required by the installation design. Use a 5.0-series LSI sibling instead when ground-fault protection is already handled elsewhere in the switchboard. The H-frame rating gives it 70 kA Icu at 380/415 V AC; within the NS630bH 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.
