Product details

Motor starting duty and overload protection

The 3RW5247-6AC04 is a SIRIUS soft starter rated for a minimum motor FLA of 200 A at 200-480 V supply, covering the common low-voltage motor range for pumps, fans, and compressors. Trip Class is selectable between CLASS 10A (default), 10E, or 20E per IEC 60947-4-2, which sets the overload protection curve to match the motor's thermal withstand during starting — CLASS 10A for standard starts, 20E for high-inertia loads.

Fieldbus integration and control options

Built-in support for PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET (with PROFIenergy) means this starter can drop into most industrial Ethernet or serial networks without an external gateway. Analog output is configurable as 4-20 mA (default) or 0-10 V via the High Feature HMI, giving the PLC a real-time current signal for monitoring motor load. Remote reset is achieved by cycling the 24 V control supply — no need to open the panel door for a manual reset after a trip.

Mounting and panel layout

Dimensions are 203 mm deep, 210 mm wide, 393 mm high — a substantial footprint that requires a backplate or sub-panel with screw-fixing provisions; not a DIN-rail snap-on device. Mounting position allows vertical surface with ±90° rotation and ±22.5° tilt forward/back, so the starter can be oriented to fit the enclosure layout without derating. Clearance requirements: 100 mm above, 10 mm in front, 75 mm below, 5 mm at the sides — plan the gland plate and cable routing to maintain these gaps for airflow and service access.

Approvals and compliance

Carries CE marking for European markets, plus UL and CSA approval for North American installations — the nameplate and declaration of conformity cover the regulatory requirements for most industrial panels. Pollution degree 3 per IEC 60947-4-2 means it is rated for industrial environments with conductive dust or occasional condensation — no additional conformal coating needed in typical machine-tool or process-plant cabinets.
