Product details

630 A distribution breaker with 150 kA interrupting capacity

The C063L42AFM is a 4-pole ComPacT NS new generation molded-case circuit breaker rated 630 A at 50 °C, from Schneider Electric's high-current distribution line. Its MicroLogic 2.0 A electronic trip unit provides L (long-time overload) and I (instantaneous short-circuit) protection, with a 20-minute thermal memory for reclose coordination after a trip.

Breaking capacity across common voltage levels

Rated Icu reaches 150 kA at 220/240 V AC and 380/415 V AC, 130 kA at 440 V AC, and 100 kA at 500/525 V AC — all at 50/60 Hz per IEC 60947-2. This covers most low-voltage distribution voltages globally. The utilisation category is A (no intentional short-time delay), so it trips instantaneously on fault.

Fixed-mount, front-connection panel integration

Mounts fixed to a backplate with a 70 mm connection pitch. Both upside and downside connections are front-facing, simplifying busbar or cable terminations in a switchboard. Dimensions are 327 mm high × 280 mm wide × 147 mm deep. The IP40 enclosure keeps out tools and fingers but not moisture — install in a dry, indoor panel. IK07 impact rating handles incidental knocks during maintenance.

Listed as current-production (active lifecycle stage). The ComPacT NS new generation is the latest platform, replacing the earlier NS630b series. No last-time-buy windows or successor part numbers are in effect.

Electrical and mechanical endurance

Rated for 10,000 mechanical cycles and 2,000 electrical cycles at full rated current and 690 V. At half current (In/2) and 690 V, electrical durability rises to 3,000 cycles; at 440 V and In/2, it reaches 4,000 cycles. This is sufficient for most distribution applications where switching frequency is low — not a contactor replacement for frequent motor starting.

Local diagnostics and metering

The MicroLogic 2.0 A trip unit includes an LCD display and ammeter function for reading load current locally. Four red LEDs indicate fault type; one yellow LED signals overload. Manual operation with no auxiliary power needed for basic tripping — the electronic trip is self-powered from the line current above a minimum threshold.

Frequently asked questions

What is the breaking capacity of C063L42AFM at 415 V?

150 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. At 440 V it is 130 kA, and at 500/525 V it is 100 kA.

What trip unit does C063L42AFM use?

It uses a MicroLogic 2.0 A electronic trip unit with L (long-time overload) and I (instantaneous short-circuit) protection, plus a 20-minute thermal memory.

Where can I buy C063L42AFM and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm offer.

What compliance standards does C063L42AFM meet?

It complies with EN/IEC 60947-2, pollution degree 3, overvoltage category III, and carries IP40 and IK07 ratings. The manufacturer provides standard compliance documentation upon request.
