Product details

It carries 2 normally-open and 2 normally-closed instantaneous contacts, rated for a maximum operational current of 10 A in AC-12 duty (resistive loads at line frequency). The size S00 footprint (45 mm wide, 57.5 mm tall, 72 mm deep) is the standard compact frame for this class in the SIRIUS family, and the screw and snap-on mounting lets it clip directly onto a DIN rail or fasten with screws into a backplate.

The 10 A AC-12 rating is the headline — it governs resistive switching at line voltage. For inductive DC loads the derating is steep: 10 A at 24 V drops to 1 A at 110 V, 0.27 A at 220 V, and 0.1 A at 690 V. That means this contactor is sized for control transformers, pilot lights, and PLC output isolation, not for motor starting.

The front carries IP20 protection.

Frequently asked questions

What is the closest functional second-source for 3RH1122-1AU60-1AA0?

The 3RH2122-2AV00 is a peer in the same SIRIUS auxiliary contactor family, but it carries a different contact configuration and coil voltage — verify the contact arrangement and coil rating before substituting. The 3RH1122-1AU60-1AA0 has 2 NO + 2 NC instantaneous contacts; the 3RH2122-2AV00 differs in its contact set and auxiliary switch extension.
