200–480 V SIRIUS Soft Starter

The 3RW5247-6AC14 is designed for compatible motor applications operating within the 200–480 V range.

Its voltage range makes it suitable for various industrial motor-control systems where controlled starting is required.

Typical applications include:

• Pumps
• Fans and blowers
• Compressors
• Conveyor systems
• Production machinery
• Material-handling equipment
• Process machinery
• Industrial ventilation systems
• OEM machinery
• Water and utility equipment

The final soft-starter selection should be based on the motor's rated current, starting conditions, load characteristics and application requirements.

470 A Rated Current

The 3RW5247-6AC14 has a rated current of 470 A, making it suitable for high-current industrial motor applications.

This capacity makes the unit useful for large motors where controlled starting is preferred over direct-on-line starting.

Potential applications include:

• Large pumps
• Heavy-duty conveyors
• Industrial compressors
• Large fans
• Blowers
• Process equipment
• Material-handling machinery
• High-power production equipment

The motor's actual current and required duty should always be verified before selecting the soft starter.

110–250 V AC Control Supply

The soft starter is specified with a 110–250 V AC control supply.

This provides the supply required for the control functions of the device and should be matched with the control architecture of the installation.

The control voltage must be verified against the complete electrical design before installation.

Screw Terminals

The 3RW5247-6AC14 features screw terminals, providing a familiar connection method for industrial electrical panels.

This type of connection can simplify wiring, commissioning and maintenance when installed according to the manufacturer's requirements.

Analog Output

A notable feature of the 3RW5247-6AC14 is its analog output.

An analog output can be used to provide a proportional electrical signal representing a configured operating value or measurement to an external monitoring or control system.

This can be useful for:

• PLC monitoring
• Process visualization
• Motor/load monitoring
• Analog instrumentation
• Control-system feedback
• SCADA integration
• Equipment diagnostics

The exact analog signal type, range and assignable process value should be verified from the applicable Siemens technical documentation before connecting it to a control system.

Controlled Motor Starting and Stopping

The SIRIUS soft starter controls motor acceleration and deceleration, helping avoid the abrupt electrical and mechanical effects associated with direct-on-line starting.

The 3RW5247-6AC14 can help provide:

• Reduced starting-current peaks
• Controlled acceleration
• Reduced mechanical shock
• Reduced torque stress
• Smoother motor starting
• Controlled stopping
• Improved equipment operation

Actual starting performance depends on the connected motor, load characteristics and configured parameters.

Integration with Automation Systems

The 3RW5247-6AC14 can be incorporated into an industrial motor-control architecture together with suitable automation and protection components.

Typical system components can include:

• PLCs
• HMIs
• Motor protection devices
• Circuit breakers
• Contactors
• Safety components
• Analog monitoring systems
• Other Siemens SIRIUS components

The analog output can be particularly useful where operating data needs to be made available to a higher-level monitoring or control system.

Applications

The Siemens 3RW5247-6AC14 can be used across various industrial applications, including:

• Industrial automation
• Heavy-duty motor control
• Pumping systems
• Water-treatment equipment
• Conveyor systems
• Compressor installations
• Industrial fans and blowers
• Production machinery
• Process plants
• Material-handling systems
• OEM machinery
• Electrical control cabinets
• Manufacturing facilities
• Industrial utility systems
