Mounting is via screw and snap-on onto 35 mm DIN rail, with a 73 mm depth, 45 mm width, and 57.5 mm height. Compliance documentation includes RoHS conformance per the substance prohibition date of October 1, 2009. The three NO contacts are rated for AC switching with arcing times of 4 to 15 ms, and DC switching at up to 10,000 operations per hour. Mechanical life is typical 30 million operations, giving a long service interval in high-cycle applications. Wire connection accepts solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².","metaTitle":"Siemens 3RH2131-1AN20 SIRIUS Auxiliary Contactor, 3 NO Conta","metaDescription":"Siemens 3RH2131-1AN20 SIRIUS auxiliary contactor, size S00, 3 instantaneous NO contacts, rated 10 A at 24 V / 230 V, screw & snap-on DIN rail mount.
