Product details

The A9N17523 is a Schneider Electric iDPN N miniature circuit breaker rated 40 A with a B curve (magnetic trip 3–5 × In) and a 1P+N pole configuration. The thermal-magnetic trip unit combines a bimetal strip for overload protection and a solenoid for short-circuit response. The 1P+N design switches the line conductor and provides a switched neutral — the neutral is not protected but is disconnected when the breaker trips, which is common in single-phase final circuits where the neutral is bonded at the source.

Integration notes

The 18 mm width per pole (2 × 9 mm pitches) means this 1P+N breaker occupies two modules on a DIN rail — standard for a single-pole switched-neutral MCB. Depth is 78 mm, height 81 mm. Tunnel terminals accept 0.33–10 mm² flexible or 0.75–16 mm² rigid upstream and downstream; wire stripping length is 13 mm, tightening torque 2 N·m. IP20 finger-safe terminals are standard for enclosed distribution boards. The toggle switch provides local ON/OFF indication.

Frequently asked questions

Who supplies A9N17523 and how is it quoted for volume purchases?

The A9N17523 is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time against an RFQ.

What is the closest alternative to A9N17523 in the iDPN N family?

Within the same iDPN N series, the key variant is the C-curve version (e.g., A9N17524) which has a magnetic trip of 5–10 × In instead of the B-curve's 3–5 × In. The B curve is better for resistive loads; the C curve handles moderate inrush from small motors or transformers. All other ratings (40 A, 1P+N, 6 kA) are identical.

What is A9N17523's listed depth?

The A9N17523 has a depth of 78 mm.

What is A9N17523's listed range?

The A9N17523 belongs to the Clario range of miniature circuit breakers.

What compliance documentation does this brand provide for A9N17523?

The A9N17523 is certified to EN/IEC 60898-1. The evidence does not list RoHS, REACH, UL, or CSA documentation; verify with the supplier at quote time if those are required.
