Product details

It carries 3 normally-open and 1 normally-closed instantaneous contacts, rated 10 A at AC-12 duty — the resistive-load curve that governs most PLC and relay interface circuits.

Mounts via screw or snap-on to a DIN rail, with the standard S00 footprint: 45 mm wide, 57.5 mm tall, 72 mm deep. Terminals accept solid conductors from 0.5 mm² up to 4 mm², with the clamping ranges split as 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), and 2x 4 mm². That covers the control wiring you'll typically run — 1.5 mm² for the coil circuit, 2.5 mm² for the contact loop back to the PLC input card. Front face is IP20 rated; the enclosure itself is designed for panel interior use where no washdown or dust ingress is expected.

Contact ratings and switching

For inductive DC switching, the numbers drop fast: 1 A at 110 V, 0.27 A at 220 V. At 230 V AC the contacts handle 6 A; at 400 V AC, 3 A; at 690 V AC, 1 A. If you're switching a DC brake coil or a contactor holding circuit, size the load against the DC voltage column — the AC-12 number won't apply. Mechanical endurance is listed at 30 million operating cycles typical for the contactor. No electrical endurance figure is given under load, so that mechanical number is the benchmark for replacement intervals in dry-circuit or lightly loaded signal switching.

Shock resistance is tested at 10g / 5 ms and 5g / 10 ms — enough for most industrial machinery but not for direct mounting on a high-impact press. Altitude limit is 2 000 m above sea level.

Frequently asked questions

What is the 3RH1131-1AH00 rated for in terms of current?

The maximum operating current at AC-12 duty is 10 A at 24 V. For inductive DC loads, derate to 1 A at 110 V, 0.27 A at 220 V. For AC loads at 230 V it handles 6 A, at 400 V it handles 3 A, and at 690 V it handles 1 A.

Where can I buy the 3RH1131-1AH00?

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

Will the 3RH1131-1AH00 drop into a panel specified around the 3RT1017-1AD02?

Both are size S00 contactors with the same 45 mm width and DIN-rail snap-on mounting, so the mechanical footprint matches. The 3RH1131-1AH00 is an auxiliary contactor (control-circuit switching) while the 3RT1017-1AD02 is a power contactor — verify the coil voltage and contact configuration match your schematic before substituting.
