The contact ratings tell you where this part fits: 10 A at 24 V and 230 V AC, 3 A at 400 V, and 1 A at 690 V. That covers most 24 VDC signal switching and 230/400 VAC pilot duty in motor control centers. Arcing time runs 10 to 15 ms, so snubber design matters if you're switching inductive loads like small solenoid valves. Wire termination accepts 2x (0.5 to 4 mm²) solid or stranded — strip length not stated, but 8 mm is standard for this terminal class. The S00 footprint keeps panel fill factor tight; three of these fit in the space of a single S2 contactor. The lifecycle stage for this order code is listed as current — meaning Siemens still lists it as an active catalog number. No end-of-life notice or successor code is recorded in the evidence.","metaTitle":"Siemens SIRIUS 3RH2131-2AB00-ZX95 Auxiliary Contactor, 3 NO,","metaDescription":"Siemens SIRIUS 3RH2131-2AB00-ZX95 auxiliary contactor, size S00, 3 NO contacts, 24 V 50/60 Hz coil, 10 A at 230 V, 73 mm depth, DIN-rail snap-on.
