Trip class is selectable between CLASS 10A (default), 10E, or 20E per IEC 60947-4-2. The voltage range is 200–480 V, covering common global low-voltage networks (208 V, 230 V, 400 V, 480 V). Confirm the line voltage falls within this window — the soft starter's phase-angle firing control needs the full range to maintain torque linearity. ## Mounting and panel fit — screw fixing with clearance rules Screw fixing is the only fastening method — no DIN-rail clip. The unit measures 203 mm deep, 210 mm wide, and 393 mm high. Plan the backplate layout with these dimensions plus the required clearances: 100 mm upwards, 10 mm forwards, 0 mm backwards, 75 mm downwards, and 5 mm at the side. The 0 mm backwards clearance means the unit can sit flush against the back panel, but the 100 mm upward gap is mandatory for airflow and cable bending radius. Mounting position allows a vertical surface with ±90° rotation and ±22.5° tilt front-to-back. ## Fieldbus connectivity and control features Built-in fieldbus support includes PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET (with PROFINET standard communication module). This covers most common automation networks — no external gateway needed for integration into Siemens S7, Rockwell ControlLogix, or Modbus-based systems. Additional control features include soft torque for gentle starts on conveyors, pump ramp down to prevent water hammer, auto-reset and remote reset (by cycling the 24 V control supply), and an analog output configurable as 4–20 mA or 0–10 V via the High Feature HMI. The error logbook is available only with special accessories. ## Lifecycle and compliance — active production, global approvals Approvals include CE marking, UL approval, and CSA approval. Pollution degree 3 per IEC 60947-4-2 means it's rated for industrial environments with conductive pollution — no additional conformal coating required for typical panel conditions.","metaTitle":"Siemens 3RW5246-6AC04 Soft Starter, 160 A, 200-480 V, SIRIUS","metaDescription":"Siemens 3RW5246-6AC04 SIRIUS soft starter, 160 A minimum, 200-480 V, Class 10A/10E/20E, PROFIBUS/Modbus/EtherNet/IP.
