Product details

The Schneider Electric EZ9F34316 is a 3-pole Easy9 miniature circuit breaker rated at 16 A with a C-curve trip characteristic, designed for distribution applications per IEC 60898-1.

Clip-on mounting to DIN rail (35 mm) — the standard for enclosure backplanes. At 54 mm wide (6 × 9 mm pitches) and 81 mm tall, it occupies three modular spaces on the rail, leaving room for adjacent breakers or accessories in a multi-pole distribution board. Tunnel-type terminals accept 1–25 mm² rigid or 1–16 mm² flexible cable; torque to 2 N·m.

Frequently asked questions

How do I get current pricing and availability for EZ9F34316?

Submit an RFQ through the storefront. Pricing and stock are confirmed at quote time; this part is sourced through independent distribution channels.

What compliance documentation does Schneider Electric provide for EZ9F34316?

The breaker is certified to IEC 60898-1, rated for isolation per that standard, and carries IP20 protection (IEC 60529). It is suitable for use in pollution degree 2 environments, with tropicalisation class 2 for humid conditions.

What is EZ9F34316's listed depth (66.5 mm) on this component line?

The depth is 66.5 mm — this is the dimension from the DIN-rail mounting face to the front of the toggle, which governs clearance behind the enclosure door or cover.

What is EZ9F34316's listed poles (3P) on this component line?

It is a 3-pole (3P) breaker, meaning it simultaneously switches and protects all three phases of a 400 V AC three-phase circuit.
