Product details

The C63H3TM630 is a Schneider Electric ComPacT NSX630H moulded-case circuit breaker, 3-pole, rated 600 A at 40 °C with a TM-D thermal-magnetic trip unit. The toggle-operated breaker mounts on a backplate or DIN rail, with front connections top and bottom.

The H rating delivers 70 kA Icu at 380/415 V AC, 65 kA at 440 V, and 35 kA at 525 V. At 220/240 V it reaches 100 kA Icu. For a 415 V distribution board fed from a transformer in the 1–2 MVA range, 70 kA gives real selectivity headroom downstream.

Thermal element tracks the 600 A rating at 40 °C; magnetic pickup is fixed. No earth-leakage module is integrated — that's a separate add-on slot if needed.

Six accessory slots are available for shunt trips, auxiliary contacts, or communication modules. Connection pitch is 45 mm. IP40 enclosure protection, IK07 impact resistance.

Frequently asked questions

Where can I buy C63H3TM630 and what is the lead time?

The part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time number is published here.

What is C63H3TM630's breaking capacity at 415 V?

70 kA Icu at 380/415 V AC per EN/IEC 60947-2. At 440 V it is 65 kA, at 500 V 50 kA, and at 690 V 20 kA.

What compliance documentation does this breaker carry?

It is certified to EN/IEC 60947-2, with IP40 and IK07 protection ratings. Pollution degree 3 and overvoltage category III apply. The manufacturer provides standard compliance documentation (declaration of conformity) upon request.
