It is designed for switching control circuits and signaling loads in industrial panels — the contacts handle 10 A at 24 V and derate to 0.26 A at 600 V, so the thermal rating governs the real load choice, not the 24 V figure alone. Mounting is screw and snap-on onto a standard 35 mm DIN rail, with a 45 mm width and 73 mm depth that fits the S00 footprint — the same envelope as the 3RT2 contactors, so it shares the same panel layout and busbar system.
The 3RH2131-1AK60 is RoHS compliant per the substance prohibition date of 10/01/2009. It carries a pollution degree 3 rating.
