Product details

The Schneider Electric EZC630H3400N is a 3-pole EasyPact EZC630H moulded-case circuit breaker rated 400 A at 40 °C, with a TM-D thermal-magnetic trip unit. Its H breaking capacity code means 50 kA Icu at 380 V AC 50/60 Hz per IEC 60947-2 — enough to handle high-fault distribution panels without cascading upstream. The same breaker delivers 70 kA Icu at 220/230 V AC and holds 50 kA Icu at 400/415 V AC, so it stays selective across common industrial supply voltages.

Fixed backplate mount, 45 mm connection pitch. Front-front wiring — both line and load connections on the front face — simplifies busbar layout in a panel. IP20 finger-safe terminals, IK07 impact resistance. The black moulded case and toggle control are standard for the EasyPact range.

Frequently asked questions

Where can I buy EZC630H3400N and how do I get a price?

We source the EZC630H3400N to order against an RFQ. Submit a request through the site; availability and current pricing are confirmed at quote time.

What is the closest alternative to EZC630H3400N in the EasyPact family?

Within the EasyPact EZC630H series, the main variant difference is the trip rating. The EZC630H3400N is the 400 A thermal-magnetic version. A 630 A variant (EZC630H3630N) exists for higher-load feeders, but it is not pin-compatible — the frame size is the same, but the trip unit and internal bus differ. No direct second-source exists outside the Schneider EasyPact line.

What compliance documentation does Schneider provide for EZC630H3400N?

The breaker is certified to EN/IEC 60947-2, GB/T 14048.2, and JIS C8201-2-2. It carries IP20 and IK07 ratings. RoHS and REACH declarations are standard with the Schneider EasyPact range; UL/CSA listing is not claimed on this variant — verify with your local Schneider representative if UL recognition is required for your jurisdiction.
