Its 3 NO + 1 NC instantaneous contacts handle 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — so the same block covers low-voltage PLC outputs up to 690 V line signals.
The 57.5 mm height, 90 mm width, and 72 mm depth keep it compact for high-density panels.
The 3RH2440-1AP00 is a common peer, but it carries a different contact arrangement (4 NO vs 3 NO + 1 NC) and a different terminal layout. The 3RH1431-1AR60 drops into the same Size S00 footprint and uses the same screw/snap-on mounting, so a panel designed for the 3RH2440-1AP00 can accept the 3RH1431-1AR60 without rewiring if the contact configuration matches the circuit. Verify the NO/NC count before swapping.
The part carries RoHS compliance with a substance prohibition date of 07/01/2006. Standard Siemens documentation includes a CE declaration and a manufacturer's declaration for REACH; UL and IEC ratings are covered in the datasheet. No specific UL file number is listed in this record, but the 6 kV surge voltage resistance and pollution degree 3 align with IEC 60947 requirements.
