Product details

Its primary job is to switch signal-level loads (PLC inputs, relay coils, pilot lights) rather than motor power, so the contact ratings are specified per voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. That spread tells you the contacts are silver-alloy, sized for control-circuit duty, not motor-circuit inrush.

Mounting and integration — fits the standard DIN-rail footprint

The S00 body is 45 mm wide and 60 mm tall, with a depth of 73 mm — a compact footprint that leaves room for adjacent devices in a crowded panel.

Contact reliability and environmental ratings

Shock resistance is 10g / 5 ms and 5g / 10 ms, adequate for most industrial machinery but not for high-vibration applications like crushers.

Frequently asked questions

Where can I buy 3RH1122-2AR60 and get current pricing?

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

Will 3RH1122-2AR60 drop into a panel specified around 3RH2122-2AV00 without rewiring?

Both are SIRIUS S00 auxiliary contactors with the same 45 mm width and screw/snap-on mounting, so they share the same DIN-rail footprint and terminal layout — no rewiring needed for the mechanical fit. The 3RH2122-2AV00 carries a different coil voltage (not specified here), so verify coil compatibility before substitution.

What compliance documentation does Siemens provide for 3RH1122-2AR60?

The part carries a RoHS compliance date of 07/01/2006, meeting EU directive 2002/95/EC. Standard Siemens documentation includes a CE declaration and manufacturer's declaration for the SIRIUS series.
