The Siemens Sirius 3RW5 range of soft starters, with their intelligent functions, offers the perfect soft starter alternative for almost any application, from simple installations to sophisticated drive requirements such as heavy-duty starting. These dependable soft starters allow you to start three-phase motors easily, reliably and smoothly. Packed with features the 3RW5 soft starters provide a range of features including automatic parameterisation, pump cleaning, and condition monitoring, making these soft starters ideal for pumps, compressors, fans, conveyors, wastewater systems and for applications the food and beverage industry.
Versatile, the Siruis 3RW5 range encompasses all of the performance classes up to 1,200 kW, ideal for a multitude of industrial applications a few examples are summarised below.
Compressor – Condition Monitoring
Designed to excel, you can evaluate the electrical data and motor active power of the soft starter, giving you the ability to condition monitor your equipment’s status. You can assess if a pump is running dry or a bearing is showing signs of fatigue and damage.
Conveyor Belt – Automatic Parameterisation
The soft start-up of conveyor belts must constantly adjust to new conditions as the starting weight changes. Using the 3RW5 auto-parameterisation function the soft starter identifies the load conditions and sets the appropriate values for optimally starting.
Sawmills – Integrated Braking
Heavy saw blades used in industrial sawing installations need a soft starting function to protect electrical and mechanical systems and you need to be able to stop saw blades quickly, the 3RW5 soft starters automatically supports DC braking and reverse braking.
Wastewater – Pump Cleaning
In wastewater applications, dirt and particles can be deposited on the pump blades reducing capacity. The pump cleaning function prevents this; integrated measurement technology detects the dirt and changes the direction of rotation as soon as limits are exceeded.
Water Supply – Pump Stop
Shutting down water pump systems can be challenging, pumps in these installations can stop immediately resulting in water hammer in pipes, couplings and valves. To prevent damage the 3RW5 range of soft starters have a pump-stop function that makes it possible to bring pumps to a controlled stop.
