Product details

It carries 2 normally-open instantaneous contacts in the S00 frame size, meaning it fits the same DIN-rail footprint as the S00 power contactors and can be ganged alongside them for interlocking or signal feedback. The contacts are rated for 10 A at 24 V, 10 A at 230 V, and derate to 0.26 A at 600 V — so the buyer needs to match the switching voltage to the load's control circuit, not assume a single current rating holds across all voltages.

Side clearance of 6 mm and 10 mm upward/downward/forward clearance keeps heat dissipation and wiring access predictable. Accepts solid or stranded wire: 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm².

Frequently asked questions

Where can I buy 3RH2122-1AQ00 and how do I get a price?

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

Will 3RH2122-1AQ00 drop into a panel that was specified around 3RH2122-2AV00 without rewiring?

Both are S00 auxiliary contactors with the same mounting footprint on 35 mm DIN rail, so mechanical fit is identical. However, the 2AV00 variant carries a different contact configuration or coil voltage — verify the wiring diagram against the existing panel before swapping.

What compliance documentation does this brand provide for 3RH2122-1AQ00?

The part carries RoHS compliance dated 10/01/2009. For UL, CSA, or IEC certifications, refer to the manufacturer's declaration or the product label on the unit.
