Product details

The Schneider Electric A9Z82440 is a 4-pole residual current circuit breaker (RCCB) from the Acti9 iID range, rated 40 A with 100 mA earth-leakage sensitivity. That covers most modern loads with rectifiers or switching supplies, not just plain resistive heaters.

Clip-on mounting on DIN rail, 8 x 9 mm pitches wide (72 mm). Neutral on the left. Strip 14 mm for top or bottom connection.

Electrical performance and coordination

Rated conditional short-circuit current of 10 kA, with a making/breaking capacity Idm of 1500 A. Impulse withstand voltage 6 kV, pollution degree 3. The RCCB is voltage-independent — it trips on residual current alone, no auxiliary supply needed. Instantaneous time delay, so it responds immediately to earth faults. Electrical durability 15,000 cycles (AC-1), mechanical 20,000 cycles.

Frequently asked questions

Who supplies A9Z82440 and how is it quoted for volume purchases?

We supply the A9Z82440 through our independent distribution channel. It is quoted to order against an RFQ; availability and current pricing are confirmed at the time of quote.

What is the closest alternative to A9Z82440 in the Acti9 family?

Within the Acti9 iID range, the closest alternative would be a different sensitivity or current rating — for example, a 30 mA version for personnel protection instead of the 100 mA equipment-protection sensitivity of this unit. The mechanical footprint and wiring are identical.

What compliance documentation does Schneider provide for A9Z82440?

The A9Z82440 is designed to EN/IEC 61008-1 and EN/IEC 61008-2-1 standards. It carries IP20/IP40 ratings per IEC 60529. For specific RoHS, REACH, or UL documentation, the manufacturer's compliance declarations are available on request.
