Product details

The Siemens 3RH2131-1AD00 is a SIRIUS auxiliary contactor, size S00, with three normally-open instantaneous contacts. Rated for switching across a wide voltage range: 10 A at 24 V and 230 V AC, down to 0.26 A at 600 V. Dimensions are 57.5 mm high, 45 mm wide, and 73 mm deep — compact enough for dense S00 panels.

Accepts solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². Screw terminals are the standard termination — no special tooling needed for field replacement. Rated for both 50 Hz and 60 Hz supply with operating ranges of 0.8 to 1.1 and 0.85 to 1.1 times rated voltage respectively.

Relative humidity rating starts at 10%, and the part carries no special storage restrictions beyond the temperature range.

Frequently asked questions

How do I get current pricing and availability for 3RH2131-1AD00?

Submit an RFQ through the distributor — pricing and stock are confirmed at quote time against your order.

Will 3RH2131-1AD00 drop into a panel specified around 3RH2131-2AK60 without rewiring?

Both are S00 auxiliary contactors with the same mounting footprint, so the mechanical swap is straightforward. The 3RH2131-1AD00 has 3 NO contacts, while the 2AK60 variant has a different contact configuration — verify your circuit needs before swapping.

What compliance documentation does this brand provide for 3RH2131-1AD00?

RoHS compliance is documented with a substance prohibition date of October 1, 2009. The part is a Siemens SIRIUS product, which typically carries CE, UL, and CSA certifications per the series standard.

What are the key ratings for 3RH2131-1AD00?

Three NO instantaneous contacts rated 10 A at 24 V and 230 V AC, with a mechanical life of 30 million operations. Dimensions are 57.5 x 45 x 73 mm.
