The C63H4TM630 is a Schneider Electric ComPacT NSX630H circuit breaker rated 600 A at 40 °C, 4 poles, with a TM-D thermal-magnetic trip unit. The toggle control and front connections suit standard panel layouts, and the 185 mm width plus 255 mm height fits backplate or DIN-rail mounting.
At 220/240 V AC the Icu reaches 100 kA, and at 690 V AC it still holds 20 kA. The Category A utilization (no intentional short-time delay) makes it a straightforward distribution breaker; selectivity with downstream devices relies on the magnetic trip curve, not a delayed trip.
The thermal-magnetic design is field-adjustable only for the magnetic pickup range — no electronic adjustments or communication options on this fixed version.
Mechanical and environmental
Rated for 15,000 mechanical cycles and 8,000 electrical cycles at 440 V at half rated current (In/2). IP40 enclosure protection means it resists tools and wires over 1 mm — fine for clean indoor panels but not washdown. IK07 impact resistance handles accidental tool drops. The 110 mm depth and 45 mm connection pitch simplify busbar and cable routing in standard switchboards.
