Product details

It carries a 24 V AC coil rated at 50/60 Hz and a continuous current rating of 10 A at 24 V, making it a standard fit for 24 V control schemes in industrial automation. The S00 footprint — 45 mm wide, 57.5 mm tall, 73 mm deep — fits the compact rail space common in distribution panels and control cabinets.

The 10 A rating at 24 V (and also at 230 V) defines the contact's thermal current capacity for auxiliary loads — pilot lights, PLC inputs, contactor coils. At higher voltages the current derates: 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, down to 0.26 A at 600 V. Mechanical endurance is listed at 30,000,000 operating cycles typical.

The screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded conductors. Spacing clearances: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side — these are the minimum air gaps to adjacent metalwork or wiring ducts for the pollution degree 3 rating. The 3 NO + 0 NC instantaneous contact configuration (3 normally open) is typical for extending the control circuit reach of a main contactor or for signaling a PLC input block.

Frequently asked questions

Will the 3RH2131-1AB00-1AA0 drop into a panel specified for the 3RH2131-2AK60?

Both are SIRIUS S00 auxiliary contactors with the same DIN-rail footprint and 45 mm width. The 1AB00-1AA0 has a 24 V AC coil and 3 NO contacts; the 2AK60 has a different coil voltage and contact arrangement. Check the coil voltage and contact count against your schematic — the mechanical fit is the same, but the electrical function may differ.
