The block is rated for a maximum of 10 A, with specific contact ratings across voltages: 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 6 A at 250 V, 3 A at 400 V, and 0.3 A at 220 V. It carries a mechanical service life of 10,000,000 switching cycles typical, and a contact reliability of 1 faulty switching per 100 million operations at 17 V, 1 mA. This part is listed as a phased-out product. The official successor is the SIRIUS 3RH2 series. ## Panel Integration and Ratings The block measures 36.5 mm wide, 37.5 mm high, and 41.5 mm deep, fitting into the size S00 footprint. The surge voltage resistance is rated at 6 kV, and the insulation voltage with degree of pollution 3 is 690 V AC.","metaTitle":"Siemens 3RH1911-1FA22-ZW96 SIRIUS Auxiliary Switch Block, 10","metaDescription":"Siemens SIRIUS 3RH1911-1FA22-ZW96 auxiliary switch block, 2 NO + 2 NC, 10 A max, screw terminals, snap-on mounting.
