Product details

Breaking capacity is rated at Idm 1500 A / Im 1500 A, with a conditional short-circuit current of 10 kA when backed by an upstream overcurrent device. That means the RCCB itself handles fault currents up to 1500 A and can be installed on networks with prospective short-circuit currents up to 10 kA, provided the upstream MCB or fuse clears the fault. The 6 kV rated impulse withstand voltage (Uimp) and pollution degree 3 suit industrial panel environments where transient surges and conductive dust are present.

IP20 finger protection on the terminals, IP40 on the modular enclosure — standard for enclosed distribution boards.

Type A earth-leakage protection class covers AC and pulsating DC faults. The 8/20 µs impulse withstand test (250 A) confirms electromagnetic compatibility with surge events on the mains. Storage temperature range -40…85 °C, operating -25…60 °C.

Frequently asked questions

Where can I buy the A9Z26440 and how do I get a price?

The A9Z26440 is sourced and quoted to order through independent distribution. Submit an RFQ for current pricing and availability — no stock count or price is published here, but the part is a standard active line and can be procured.

What is the A9Z26440's rated sensitivity and protection type?

500 mA earth-leakage sensitivity, Type A — covers sinusoidal AC and pulsating DC fault currents. Instantaneous trip, voltage-independent residual current detection.

What standards does the A9Z26440 comply with?

EN/IEC 61008-1 and EN/IEC 61008-2-1. The impulse withstand is 8/20 µs, 250 A. Pollution degree 3, rated insulation voltage 500 V AC.
