It's the part you reach for when the main contactor's auxiliary block is full and you need extra NO contacts for a PLC input, a status lamp, or a permissive interlock.
At 24 V the contacts are rated 10 A — that's the full resistive load for a DC control circuit. At 230 V AC the rating drops to 6 A, and at 400 V AC it's 3 A. The 690 V rating of 1 A tells you this is a control-voltage contactor, not a power-switching device.
The 3RH2131-2AK60 is a peer in the same SIRIUS family with a similar contact configuration, but verify the coil voltage and terminal arrangement against your panel wiring before substituting — the 3RH1131-2AF00 uses screw and snap-on mounting with 2x (0.25...2.5 mm²) solid wire capacity, which may differ from the peer's termination.
Both are size S00 with the same 45 mm width and snap-on DIN rail mounting, so the footprint is identical. The terminal wiring capacity (2x 0.25...2.5 mm² solid) is also the same. The main difference is the contact arrangement — the 3RH1131-2AF00 has 3 NO + 0 NC, while the peer may carry a different NO/NC count. Check your schematic before swapping.
