The control supply is 20.4...26.4 V DC, and the main operating voltage range is 340...460 V at 50/60 Hz. For a commissioning engineer, the AS-Interface address is assigned via the bus master; the two inputs can be mapped to start/stop or interlock signals without additional wiring back to a remote I/O rack. ## Panel fit and environmental limits The enclosure measures 205 mm deep, 290 mm wide, and 215 mm high, with IP54 protection — suitable for control cabinets in dry indoor industrial environments where dust and splashing water are occasional, not continuous washdown.","metaTitle":"Siemens 3RK4320-5JQ64-0BA3 SIRIUS Motor Starter, 4 A","metaDescription":"Siemens SIRIUS 3RK4320-5JQ64-0BA3 motor starter MCU for AS-Interface. 4 A rated at 400 V AC-3, Class 10, DC control.
