The Siemens 3RW5225-1AC14 is a SIRIUS soft starter designed for controlled starting and stopping of compatible industrial motors. It supports a 200–480 V motor voltage range, has a 63 A rated current, and uses a 110–250 V AC control supply. The device features screw terminals and an analog output, making it suitable for industrial motor-control panels, automation systems and process applications.
The soft starter helps provide controlled motor acceleration and deceleration, reducing the sudden electrical and mechanical stresses associated with direct-on-line starting.
The 3RW5225-1AC14 is designed for compatible motor applications operating within the 200–480 V range.
Its broad voltage range makes it suitable for different industrial motor-control installations where controlled starting and stopping are required.
Typical applications include:
The correct soft starter should be selected according to the motor's rated current, load characteristics, starting conditions and application duty.
The 3RW5225-1AC14 has a rated current of 63 A, making it suitable for compatible industrial motor applications requiring controlled starting and stopping.
Potential applications include:
The motor's actual rated current and operating conditions should be verified before selecting the soft starter.
The product is specified with a 110–250 V AC control supply.
This control supply should be matched with the electrical control architecture of the installation to ensure correct operation.
The 3RW5225-1AC14 uses screw terminals for electrical connections.
This provides a familiar connection method for industrial panel builders and maintenance teams and supports straightforward installation and servicing when wiring is carried out according to the manufacturer's requirements.
A key feature of the 3RW5225-1AC14 is its analog output.
The analog output can be used to provide a configured electrical signal to an external monitoring or automation system.
This can be useful for:
The exact analog signal type, range and assignable value should be verified against the applicable Siemens documentation before connection.
The 3RW5225-1AC14 controls motor acceleration and deceleration to provide a smoother starting and stopping process.
It can help reduce:
Actual performance depends on the connected motor, load characteristics and configured soft-starter parameters.
The 3RW5225-1AC14 can be incorporated into a complete motor-control system alongside compatible equipment such as:
The analog output can provide additional operating feedback to a compatible control or monitoring system.
