Product details

It combines a 20 A thermal-magnetic trip (C-curve, 5...10 x In magnetic threshold) with integrated 30 mA Type AC earth-leakage detection in a single 4-module (9 mm pitch) DIN-rail unit.

Mounts on DIN rail with neutral on the left side. The toggle provides local ON/OFF indication, and the contact position indicator confirms the state of the main contacts without needing to open the panel.

The voltage-independent residual current trip operates instantaneously at 30 mA sensitivity, providing supplementary protection against direct contact. Electrical and mechanical durability are both rated at 20,000 cycles per IEC 61009.

Frequently asked questions

Where can I buy A9N19666 and how do I get a price?

The A9N19666 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is A9N19666's Type AC rating?

The A9N19666 is a Type AC residual-current device, meaning it detects sinusoidal AC earth-leakage currents only. It is the standard type for general-purpose circuits without non-sinusoidal or pulsating DC fault currents.

What is the breaking capacity of A9N19666?

The A9N19666 has a 6000 A Icn breaking capacity at 230 V AC, conforming to EN 61009. This is sufficient for most residential and light commercial distribution boards where the prospective short-circuit current is below 6 kA.
