Product details

Integrator note — 3RH1131-2GG20

It carries 3 normally-open and 1 normally-closed instantaneous contacts, rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for most PLC output and relay interposing duties. The front face is IP20, so it's safe for open-panel use with no additional cover.

Contact ratings and wiring

The 10 A rating at 24 V is the highest thermal current; at 110 V the rating drops to 1 A, and at 690 V it's 1 A. For AC-15 switching (solenoid valves, contactor coils), the 50 Hz make/break ratio is 0.8–1.1 at rated voltage.

Shock resistance is 10g for 5 ms and 5g for 10 ms.

Frequently asked questions

Where can I buy 3RH1131-2GG20 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the closest functional alternative to 3RH1131-2GG20?

The 3RH2131-2AK60 is a higher-rated sibling in the same SIRIUS family — it shares the S00 footprint and 3 NO + 1 NC contact arrangement but offers a different coil voltage (230 V AC vs the 3RH1131-2GG20's 24 V DC). Check coil compatibility before substituting.

What compliance documentation does the 3RH1131-2GG20 carry?

It complies with RoHS (substance prohibition date July 1, 2006) and is designed to meet IEC/EN 60947-5-1. The SIRIUS series typically carries UL, CSA, and CE marks — confirm specific certification markings on the nameplate or request a declaration of conformity.
