For DC switching at 24 V the rated current is 10 A, dropping to 0.26 A at 600 V. The contactor's mechanical endurance is 30 million operating cycles typical. The coil is rated for 50/60 Hz at 400 V, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz. Arcing time spans 10 to 15 ms. The 3RH2140-1AV00 occupies a 45 mm wide footprint on the DIN rail, with a depth of 73 mm and height of 57.5 mm. Terminals accept solid or stranded conductors: 2× (0.5 to 1.5 mm²), 2× (0.75 to 2.5 mm²), or 2× 4 mm². Relative humidity minimum is 10 %. The product carries a substance prohibition date of 10/01/2009, indicating RoHS compliance from that date onward. Lifecycle status is current production — the 3RH2140-1AV00 is an active catalog item in the SIRIUS portfolio, not subject to phase-out or end-of-life notification at this time.","metaTitle":"Siemens 3RH2140-1AV00 SIRIUS Auxiliary Contactor, 4 NO, S00","metaDescription":"Siemens 3RH2140-1AV00 SIRIUS auxiliary contactor, 4 NO contacts, size S00, 45 mm wide, 73 mm deep.
