C063H450FM – ComPacT NS630bH 4P 630 A, 70 kA Icu at 380/415 V MCCB.
The Schneider Electric C063H450FM 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 5.0 trip unit delivering long-time overload, short-time delay and instantaneous short-circuit protection (LSI), is fixed-mounted and manually operated, and carries a 690 V rated operational voltage for industrial distribution switchboards.
Its LSI trip unit adds an adjustable short-time delay (Isd, tsd) on top of the long-time overload and instantaneous stages, which lets it hold a short-time withstand for selective coordination with downstream breakers instead of tripping instantaneously on every fault. The H-frame rating gives it 70 kA Icu at 380/415 V AC; within the NS630bH line this is the class to pick when the calculated prospective short-circuit current at the installation point is at or below that figure without derating to the L-frame. 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.
