Product details

Rated 45 A at 50 °C on a C-curve, with 100 mA earth-leakage sensitivity and 10 kA Icn breaking capacity at 230 V AC.

At 82 mm deep and 118 mm tall, it clears most 100 mm-deep enclosures — but check gland-plate clearance if the busbar runs behind the RCBO. Neutral is on the left, which matters for pre-wired busbar alignment in Acti9 distribution boards.

Designed to BS EN 61009-1, the harmonised standard for RCBOs. Suitability for isolation confirmed, with an ON/OFF contact position indicator and provision for padlocking (Ø 4 mm padlock). IP20 finger protection — panel-mount only, not for wet environments.

Frequently asked questions

Where can I buy A9D18845 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is the breaking capacity of A9D18845?

10,000 A Icn at 230 V AC, 50/60 Hz — sufficient for most commercial and light industrial distribution subcircuits where the prospective fault current stays under that threshold.

What earth-leakage sensitivity does A9D18845 have?

100 mA, which suits distribution circuits where 30 mA devices would nuisance-trip on cable capacitance or equipment leakage.
