Product details

The thermal-magnetic trip unit handles the overload side. Breaking capacity is 4500 A Icn at 230 V AC, 50/60 Hz, conforming to EN/IEC 60898-1.

Width is 18 mm (2 x 9 mm pitches), so it occupies two modules on the rail — one for the protected pole, one for the switched neutral. Neutral position is left, which is standard for single-phase iDPN units. Tunnel-type terminals accept 0.75 to 16 mm² rigid or 0.33 to 10 mm² flexible on both upstream and downstream sides. The IP20 finger-safe protection is standard for enclosed panel mounting.

Tropicalisation is level 2 per IEC 60068-1 (damp heat, 95% RH at 55 °C). Operating altitude is 2000 m. Earth-leakage protection requires a separate block — this is not an RCBO.

Durability and service life

Both electrical and mechanical durability are rated at 20,000 cycles. That is typical for a residential-grade MCB and covers the expected life of the installation. The toggle control provides local ON/OFF indication.

Frequently asked questions

Where can I buy the A9N21535 and get a price?

The A9N21535 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the closest alternative to the A9N21535 in the same family?

Within the Clario iDPN range, the closest alternative would be a different current rating or curve code — the A9N21535 is a 6 A B-curve. For a C-curve at the same 6 A rating, the order code would differ by the curve letter in the part number. The form factor, terminal specs, and breaking capacity are identical across the iDPN range.

What is the A9N21535's depth?

The depth is 78 mm, with a height of 81 mm and width of 18 mm (2 x 9 mm pitches).

What compliance documentation does Schneider provide for the A9N21535?

The A9N21535 is certified to EN/IEC 60898-1, with pollution degree 3 per IEC 60947-1, limitation class 3, and tropicalisation level 2 per IEC 60068-1. Standard RoHS and REACH declarations are available from Schneider Electric.
