Product details

The Schneider Electric EZC630N4400N is a 4-pole EasyPact EZC630N circuit breaker rated 630 A at 40 °C with a TM-D thermal-magnetic trip unit. It is marked Category A, meaning it is not intended for selective coordination with other breakers in series — plan for full discrimination upstream if needed.

Deployment context

This breaker mounts fixed to a backplate with front-front connections — no DIN-rail clip, so panel layout needs dedicated mounting holes and busbar takeoffs. The 185 mm width and 255 mm height determine the cutout and enclosure fill factor. IP20 means finger-safe but not washdown; install inside a locked panel. IK07 gives basic impact resistance for the enclosure face.

Designed and tested to EN/IEC 60947-2 (circuit-breaker standard), EN/IEC 60947-1 (general rules), JIS C8201-2-2, and GB/T 14048.2.

Frequently asked questions

How do I get current pricing and availability for EZC630N4400N?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is the breaking capacity of EZC630N4400N at 440 V?

36 kA Icu at 440 V AC 50/60 Hz per IEC 60947-2. At 220/230 V it is 40 kA; at 380 V and 400/415 V it is also 36 kA.

What does the TM-D trip unit mean?

TM-D is a thermal-magnetic trip with fixed magnetic setting at 5000 A. The thermal element provides overload protection; the magnetic element handles short-circuit protection. No earth-leakage protection is built in.
