Schneider Electric C063S4NAFM ComPacT NS630bNA 4P 630 A Fixed Switch Disconnector

The Schneider Electric C063S4NAFM is a 4-pole ComPacT NS630bNA switch disconnector rated 630 A AC-23A, used for isolating and controlling distribution circuits without overcurrent protection. It is fixed-mounted, manually operated, carries a 690 V rated operational voltage, and provides suitability-for-isolation certified to IEC 60947-3 for lockout-tagout procedures on incoming feeders and bus-tie points.

Selection Notes

The C063S4NAFM isolates and controls the circuit without overcurrent protection, so it belongs upstream or downstream of a dedicated breaker rather than as standalone circuit protection. Choose the 4-pole version for a 3-phase-only distribution board and the 3-pole version when the neutral conductor also needs to be switched. The 690 V AC rated operational voltage and IEC 60947-3 suitability-for-isolation rating make it a direct fit for main incomer or bus-tie isolation points in ComPacT NS630b switchboards.
