Product details

The Schneider Electric EZ9R34425 is a 4-pole residual current circuit breaker (RCCB) from the Easy9 range, rated 25 A with 30 mA earth-leakage sensitivity and Type AC protection.

Clip-on mounting to DIN rail, neutral on the left, 18 mm phase-to-phase connection pitch. The 72 mm width (8 x 9 mm pitches) and 72 mm depth fit standard modular enclosures; tunnel terminals accept up to 35 mm² rigid or 25 mm² flexible, torqued to 3.5 N·m.

The 25 A rated current and 500 A making/breaking capacity suit it for final sub-circuits feeding lighting or general-purpose socket outlets in 400 V three-phase systems. The 30 mA sensitivity provides personal protection against indirect contact and supplementary protection against direct contact, per IEC 61008-1. Pollution degree 2 and IP20 make it suitable for clean, dry indoor panels only — not for washdown or outdoor locations.

Frequently asked questions

Where can I buy EZ9R34425 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability.

What compliance documentation does Schneider provide for EZ9R34425?

The part is designed to IEC 61008-1. For RoHS, REACH, and other compliance documentation, refer to the manufacturer's official declarations available on request.

What is the closest alternative to EZ9R34425 in the Easy9 family?

Within the Easy9 range, the closest peer would be a 4-pole RCCB with the same 30 mA sensitivity and Type AC characteristic but a different rated current — for example, a 40 A variant. The mechanical footprint and connection pitch are identical, so swapping requires only verifying the load current matches the new rating.
