Product details

What the 36 kA breaking capacity means for your panel

The A9F68240 is a 40 A, 2-pole miniature circuit breaker from the Schneider Acti9 iT60 range, with a C curve and thermal-magnetic trip unit. Its headline rating is a 36 kA breaking capacity (Icu) at 12–133 V AC, which drops to 20 kA at 220–240 V and 10 kA at 380–415 V — the figure that governs your SCCR coordination downstream.

DIN-rail integration and terminal work

Terminals accept 1–35 mm² rigid or 1–25 mm² flexible copper; strip 14 mm and torque to 3.5 N.m. The removable comb busbar is installed from the factory, so you can daisy-chain phases across adjacent breakers without extra wiring. IP20 B finger-safe protection on the front face; the back and terminals are live when busbar is energized — standard for this class.

Standards compliance and approvals

Dual-rated to EN/IEC 60898-1 (for household and similar installations) and EN/IEC 60947-2 (for industrial applications). Suitability for isolation is confirmed under both standards. Tropicalisation class 2 per EN/IEC 60068-2-78 (95% RH at 55 °C) covers humid environments without derating.

Frequently asked questions

Where can I buy A9F68240 and how do I get a price?

The A9F68240 is sourced and quoted to order against an RFQ through independent distribution channels. Submit an RFQ; availability and current pricing are confirmed at quote time.

What is A9F68240's breaking capacity at 400 V?

At 400 V AC 50/60 Hz, the A9F68240 has a 10 kA Icn per EN/IEC 60898-1 and a 10 kA Icu at 380–415 V per EN/IEC 60947-2.

What does the C curve mean on this breaker?

The C curve means the magnetic trip threshold is 5 to 10 times the rated current (In). For the 40 A A9F68240, the magnetic tripping limit is 8 x In ±20%, so it trips magnetically between roughly 256 A and 384 A — suited for general-purpose loads like lighting, socket circuits, and small motors with moderate inrush.
