Product details

It carries 3 normally-open instantaneous contacts and 0 normally-closed, rated 10 A in AC-12 duty — that's the resistive load curve for solenoid and relay loads at line voltage, so it handles the pilot-duty switching typical in a 24 VDC or 230 VAC control loop without derating concerns.

Contact ratings and switching

AC-12 rating at 10 A covers the resistive control loads — contactors, relays, solenoid valves — at 24 V through 230 V. For inductive DC switching, the 24 VDC rating is 10 A, dropping to 1 A at 110 VDC and 0.27 A at 220 VDC. The contacts are rated for 30 million mechanical operations typical, so in a cycling application like a conveyor interlock it outlasts the panel it's in. No leading, lagging, or make-before-break contacts — all three are standard instantaneous NO.

Shock rated at 10g / 5 ms and 5g / 10 ms, which covers most vibration profiles in pump skids and conveyor drives. Maximum operating altitude 2 000 m without derating.

Frequently asked questions

Where can I buy 3RH1131-2AC00-0TK0 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time.

What is the closest functional second-source for 3RH1131-2AC00-0TK0?

The 3RH2131-2AK60 is a similar SIRIUS auxiliary contactor but in size S2 with a different contact configuration — it does not drop into the same DIN footprint or wiring plan without panel rework. For a direct size S00 replacement, stick with the 3RH1131 family.

What is the depth of 3RH1131-2AC00-0TK0?

73 mm depth, with a width of 45 mm and height of 60 mm — fits the standard S00 contactor footprint.

What wire sizes does the 3RH1131-2AC00-0TK0 accept?

Solid conductors from 0.25 mm² up to 2.5 mm² per terminal, with two conductors per clamp allowed.

Will 3RH1131-2AC00-0TK0 drop into a panel wired for 3RH2131-2AK60?

No — the 3RH2131-2AK60 is a size S2 contactor with a different mounting footprint and terminal layout. The 3RH1131-2AC00-0TK0 is size S00 and requires its own DIN rail spacing and wiring plan.
