Product details

The Schneider Electric C63V42D630 is a ComPacT NSX630HB1 moulded-case circuit breaker (MCCB) rated 630 A at 40 °C, 4 poles, with a MicroLogic 2.3 electronic trip unit. It delivers 85 kA Icu at 500 V AC 50/60 Hz per IEC 60947-2, making it a high-breaking-capacity choice for distribution panels where fault levels are substantial.

The 630 A trip rating at 40 °C sets the continuous current limit; above that ambient, derating applies per the manufacturer's curve. Overvoltage category III confirms it is intended for fixed-installation distribution boards, not downstream equipment. The IP40 front face and IK07 impact resistance suit it for enclosed panel mounting where occasional tool contact is expected. Mechanical durability is 15000 cycles. For a 630 A frame, these numbers are typical for distribution duty — not for frequent switching under load. If your application cycles the breaker daily under load, expect reduced electrical life.

The 185 mm width, 255 mm height, and 110 mm depth require a cutout or mounting footprint that fits standard 600 mm wide enclosures with room for cable bending radius. Front connections both upside and downside — plan for front-access gland plates. Neutral is on the left.

Frequently asked questions

What is C63V42D630's breaking capacity?

85 kA Icu at 500 V AC 50/60 Hz per IEC 60947-2, with 80 kA at 525 V and 75 kA at 660/690 V. The breaking capacity code is HB1.

What trip unit does C63V42D630 use?

A MicroLogic 2.3 electronic trip unit providing L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous short-circuit) protection. It has a 20-minute thermal memory.

What is the closest alternative to C63V42D630 in the same family?

Within the ComPacT NSX range, the closest peer is the same frame size (NSX630) with a different breaking capacity code — for example, an H1 (50 kA at 500 V) or H2 (70 kA) variant. The C63V42D630 is the HB1 (85 kA) version. The physical footprint, trip unit slot compatibility, and mounting are identical across these; the difference is only the interrupting rating. If your fault study shows 85 kA is not required, a lower-kA variant saves cost. If you need more, the NSX630 frame tops out at this HB1 level.
