Product details

Part identity and what it does

It carries three normally-open and one normally-closed instantaneous contacts, rated for switching at voltages from 24 V up to 690 V.

The 45 mm width and 73 mm depth fit the S00 footprint, and the mounting position allows +/-180° rotation on a vertical surface, plus +/-22.5° tilt forward and back. That flexibility helps when you're squeezing it into a crowded enclosure.

Rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — these are the thermal current ratings for the auxiliary contacts. That's the kind of number that matters when you're using these contacts to switch a PLC input or a safety circuit.

Environmental and mechanical specs

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

Frequently asked questions

What is the coil voltage for this auxiliary contactor?

The coil is rated 24 VAC, suitable for both 50 Hz and 60 Hz supply.

What is the depth of the 3RH1131-2AB00-0TK0?

The depth is 73 mm.

What wire size does the terminal accept?

The solid terminal accepts 2x (0.25 to 2.5 mm²) conductors.

Will 3RH1131-2AB00-0TK0 drop into a panel specified around 3RH2131-2AK60?

Both are SIRIUS S00 auxiliary contactors with the same 45 mm width and DIN-rail mounting, so the footprint and mounting are compatible. The main difference is the contact configuration and coil voltage — the 3RH2131-2AK60 has a different contact arrangement and 24 VDC coil, so verify your control circuit voltage and contact count before swapping.

Where can I buy the 3RH1131-2AB00-0TK0?
