The Siemens 3RW5245-6AC14 is a high-current SIRIUS soft starter designed for controlled starting and stopping of industrial motors. It supports a 200–480 V motor voltage range, a rated current of 315 A, and a 110–250 V AC control supply. The soft starter features screw terminals and an analog output, making it suitable for industrial motor-control and automation applications.
The analog output provides an additional interface for transmitting configured operating information to a compatible monitoring or control system.
The 3RW5245-6AC14 is designed for compatible motor applications operating within the 200–480 V range.
This voltage range makes the soft starter suitable for a wide range of industrial motor-control systems where controlled starting and stopping are required.
Typical applications include:
The final selection should always consider the motor rating, starting conditions, load characteristics and application requirements.
The 3RW5245-6AC14 has a rated current of 315 A, making it suitable for high-current industrial motor applications.
This current capacity allows the soft starter to be used for compatible large motors where controlled acceleration and deceleration are required.
Potential applications include:
The motor's actual rated current, duty and starting requirements should be verified before selecting the soft starter.
The soft starter is specified with a 110–250 V AC control supply.
This provides the control power required for the device and should be matched with the control architecture of the industrial installation.
The control supply must be checked against the complete system design before installation.
The 3RW5245-6AC14 uses screw terminals for electrical connections.
This provides a familiar connection method for electrical panel builders and maintenance teams and supports straightforward installation when wiring is carried out according to the manufacturer's requirements.
A key feature of the 3RW5245-6AC14 is its analog output.
The analog output can be used to transmit a configured electrical signal representing a relevant operating value to an external monitoring or automation system.
This can be useful for:
The exact analog output signal, range and assignable value should be verified against the applicable Siemens documentation before connection.
The SIRIUS soft starter controls motor acceleration and deceleration, helping reduce the abrupt electrical and mechanical effects associated with direct-on-line starting.
The 3RW5245-6AC14 can help provide:
Actual motor-starting performance depends on the motor, load characteristics and configured parameters.
The 3RW5245-6AC14 can be incorporated into a complete industrial motor-control system with compatible equipment such as:
The analog output can be useful where selected operating information needs to be available to a higher-level control or monitoring system.
