Rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, the current capacity drops as circuit voltage climbs — a standard contact derating curve that matters when you're switching a 400 V control transformer secondary or a 690 V panel indication lamp. Mounts via screw or snaps onto a DIN rail — the S00 footprint is the smallest Siemens contactor frame, so this auxiliary block takes 45 mm width and 57.5 mm height on the rail, with 72 mm depth including the terminals. ## Contact ratings and reliability Contact reliability is specified as one incorrect switching operation per 100 million cycles at 17 V, 1 mA — a dry-circuit rating that matters for PLC inputs or low-energy signal paths where oxide films on silver contacts can cause intermittent opens. The mechanical endurance is 30 million switching operations typical for the contactor frame, which is the service life before the spring set or armature wears out — not the electrical life under load, which will be shorter depending on the switched current.","metaTitle":"Siemens 3RH1131-1AN60 SIRIUS Auxiliary Contactor, 3 NO, S00","metaDescription":"Siemens SIRIUS 3RH1131-1AN60 auxiliary contactor, size S00, 3 NO contacts, screw/snap-on mount, IP20 front.
