Product details

What this basic frame is and what it needs

The C63F3 is a ComPacT NSX630F basic frame — a 3-pole, 630 A molded-case switch housing with no trip unit fitted. You select and install a separate trip unit (electronic or thermal-magnetic) to define the protection curve. The frame carries a 36 kA Icu at 415 VAC and an 85 kA breaking capacity at 240 VAC per UL 508, so it handles high-fault service-entrance or distribution positions where the trip unit is specified later.

At 240 VAC the frame clears 85 kA (UL 508); at 480 VAC it clears 35 kA (UL 508); at 600 VAC it clears 20 kA (UL 508). Under IEC 60947-2 the Icu values are 40 kA at 220/240 VAC, 36 kA at 380/415 VAC, 30 kA at 440 VAC, 25 kA at 500 VAC, 20 kA at 525 VAC, and 10 kA at 660/690 VAC.

The frame mounts fixed to a backplate (not DIN rail). Connection pitch is 45 mm. Both line and load connections are front-access, which simplifies busbar or cable routing in a panel where the breaker is mounted in a row. The front face carries Class II electrical shock protection, so no additional insulation cover is required on the operator side. IP40 enclosure protection keeps out tools and small debris; IK07 impact resistance handles incidental contact during panel work.

The C63F3 is designed and certified to EN/IEC 60947-2 (low-voltage switchgear and controlgear) and UL 60947-4-1 (contactors and motor-starters). Overvoltage category III suits fixed-installation distribution boards. The manufacturer provides the standard declaration of conformity and UL recognition documentation with the shipment.

Frequently asked questions

What is C63F3's breaking capacity at 415 VAC?

The C63F3 has a 36 kA Icu (ultimate breaking capacity) at 380/415 VAC 50/60 Hz per IEC 60947-2, and the same 36 kA Ics (service breaking capacity) at that voltage level.

What trip unit does the C63F3 require?

The C63F3 is a basic frame without a trip unit. It requires a separately ordered trip unit (electronic or thermal-magnetic) to define the overload and short-circuit protection settings. The frame accepts standard ComPacT NSX630 trip units.

Where can I buy C63F3 and what is the lead time?

The C63F3 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for the exact lead time and price for your quantity.

What compliance documentation does Schneider provide for C63F3?

Schneider Electric provides a declaration of conformity to EN/IEC 60947-2 and UL 60947-4-1 with the C63F3. The frame is suitable for isolation per IEC 60947-2 and carries pollution degree 3 and overvoltage category III ratings.
