For DC switching, the contacts handle 10 A at 24 V, 4.7 A at 60 V, and 1.2 A at 220 V. These ratings are per the datasheet and define the maximum continuous current the contacts can make and break at the stated voltage under the specified duty. The contactor uses the S00 frame size. Dimensions: 70 mm high, 45 mm wide, 73 mm deep. Rated for pollution degree 3. Relative humidity minimum is 10 %. Substance prohibition date is 10/01/2009. These are the minimum air gaps needed to maintain rated insulation and to allow heat dissipation. The S00 frame width of 45 mm means it occupies three DIN rail module spaces (one module = 15 mm). When wiring, the screw terminals accept 2x (0.5 to 4 mm²) solid or stranded conductors — sufficient for control-circuit wiring up to 4 mm². ## Switching Performance Mechanical life is typical 30 million operating cycles. Maximum operating frequency for DC switching is 10,000 operations per hour.","metaTitle":"Siemens SIRIUS 3RH2131-2AF00 Auxiliary Contactor, S00, 3 NO,","metaDescription":"Siemens SIRIUS 3RH2131-2AF00 auxiliary contactor, size S00, 3 NO contacts, rated 10 A at 230 V AC.
