Product details

The Schneider Electric A9N60724 is a 3-pole miniature circuit breaker from the Acti9 C120 range, rated 100 A at 40 °C with a D tripping curve. That's the standard for commercial and light industrial distribution — not a heavy industrial main, but solid for a sub-panel or machine feeder.

The 81 mm width (9 mm pitch × 9) means it takes up nine module spaces on the rail. That's a known footprint: if you're replacing an existing C120 or similar 3P 100 A breaker, the slot count is the same. Strip length is 15 mm.

Frequently asked questions

Where can I buy the A9N60724 and get current pricing?

This part is sourced through our independent distribution channel and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ and we'll get you a firm number.

What is the A9N60724's depth on the DIN rail?

The overall depth is 73 mm from the front of the DIN rail to the back of the breaker body.

What compliance documentation does the A9N60724 carry?

The breaker is certified to EN/IEC 60947-2, with tropicalisation class 2 per IEC 60068-1, pollution degree 3, overvoltage category III, and suitability for isolation per EN/IEC 60947-2. It also carries IP20 protection per IEC 60529.
