Product details

It carries 1 NC and 3 NO auxiliary contacts rated for AC-12 switching at 6 A maximum, with a 230 V rated value of 10 A. The AC coil draws 37 VA pick-up and 5.7 VA holding. Mechanical endurance is 30 million operations, and contact reliability is specified at 1 faulty switching per 100 million operations at 17 V, 1 mA — a figure that matters for PLC-level signal integrity.

Switching capability and thermal limits

Rated for 10 000 switching cycles per hour on both AC and DC loads. The AC-12 rating (6 A) governs resistive and solid-state loads.

Frequently asked questions

Will 3RH6131-1AF00 drop into a panel specified around 3RH6131-1AP00 without rewiring?

Yes, for the most part. Both are S00 SIRIUS contactor relays with the same 1 NC + 3 NO contact arrangement and identical mounting footprint (73 mm depth, 45 mm width, snap-on DIN rail). The difference is the coil: 3RH6131-1AF00 has an AC coil, while 3RH6131-1AP00 has a DC coil. If the panel was wired for DC control voltage, the AC coil on this part will not pull in — verify the control supply before substituting.

What are the key dimensions of 3RH6131-1AF00?

Depth 73 mm, width 45 mm, height 57.5 mm. These match the standard S00 SIRIUS contactor footprint.
