For DC-13 loads the ratings are lower: 4.7 A at 60 V, 1.2 A at 220 V, 0.5 A at 440 V, and 0.26 A at 600 V. That DC curve governs the fit for valve-positioner or DC-brake circuits; if your load exceeds the curve at the applied voltage, the contacts will weld. Mechanical endurance is rated at 5 million typical operations, which for a control contactor cycling once per minute yields about nine years of service before the spring set fatigues. ## Mounting and Clearance Constraints The contactor occupies 73 mm depth, 90 mm width, and 57.5 mm height — the S00 footprint. Relative humidity minimum is 10 %. The substance prohibitance date is 10/01/2009, indicating RoHS compliance for that effective date. The contactor is rated for 50/60 Hz supply (0.8...1.1 x rated voltage at 50 Hz, 0.85...1.1 at 60 Hz).","metaTitle":"Siemens SIRIUS 3RH2422-1AU00 Auxiliary Contactor, 2 NO, S00,","metaDescription":"Siemens SIRIUS 3RH2422-1AU00 auxiliary contactor, 2 NO contacts, size S00, 73 mm depth, screw and snap-on 35 mm DIN rail mounting.
