The 3RH2422-1AU00 carries a 10 A rated current at 24 V and 230 V (AC-15 duty), so it reliably switches PLC outputs, relay coils, and solenoid valves in the typical 24 VDC or 230 VAC control loop. 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).
