Product details

It protects a single-phase final subcircuit (1P + N) at 40 A rated current with a C-curve magnetic trip (5–10 × In) and integrated 300 mA earth-leakage protection. The breaking capacity is 4500 A Icn at 230–240 V AC, 50 Hz, certified to EN/IEC 61009-2-1, which covers the majority of residential and light commercial distribution boards where the prospective fault current stays under that level.

Clip-on mounting to DIN rail (EN 60715). The 36 mm width (4 × 9 mm pitches) and 85 mm height fit standard modular enclosure cutouts. IP20 on the body, IP40 inside the modular enclosure.

Frequently asked questions

Where can I buy the A9D44640 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote to confirm availability and current pricing.

What is the breaking capacity of the A9D44640?

4500 A Icn at 230–240 V AC, 50 Hz, conforming to EN/IEC 61009-2-1. This is the unconditional short-circuit rating for the RCBO.

What standards does the A9D44640 comply with?

EN/IEC 61009-2-1 for RCBOs. Overvoltage category III per IEC 60364. Pollution degree 3. Tropicalisation class 2 per IEC 60068-1.
