Product details

Integrator note — SIRIUS 3RH1122-2AN10

The Siemens 3RH1122-2AN10 is a SIRIUS auxiliary contactor in the compact S00 frame, rated for 10 A in AC-12 duty (resistive loads at 24 V). The front face carries IP20 finger protection; the contactor itself is not sealed against washdown. Shock resistance is 10g / 5 ms and 5g / 10 ms — suitable for machine-mounted applications with moderate vibration. The auxiliary contact configuration provides 2 normally-open instantaneous contacts (no delayed, leading, or lagging switching).

Side clearance is 0 mm to adjacent devices; no additional spacing is required. The S00 footprint (45 x 60 x 73 mm) is shared across the SIRIUS modular contactor range, simplifying panel layout.

Frequently asked questions

Where can I buy 3RH1122-2AN10 and how is it quoted?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest functional alternative to 3RH1122-2AN10?

The 3RH2122-2AV00 is a peer in the same SIRIUS family but carries a different coil voltage and contact arrangement — verify the specific coil and contact count before substituting.

What is the depth of 3RH1122-2AN10?

The depth is 73 mm.

What conductor sizes does 3RH1122-2AN10 accept?

It accepts solid conductors from 0.25 to 2.5 mm² per terminal.

Will 3RH1122-2AN10 drop into a panel specified for 3RH2122-2AV00?

Both share the S00 footprint and DIN-rail mounting, so the mechanical fit is the same. However, verify the coil voltage and contact configuration — the 3RH2122-2AV00 may differ in those electrical ratings.
