The semiconductor starter Sirius 3RW44 from Siemens is used for soft motor starting and stopping. Unlike the basic configuration, this model is designed for use in high operating conditions.
One of the main advantages of starters of this type is their compact design and ease of mounting. They can be used in the most limited conditions of the control unit. In addition, minimal energy losses and high motor overload protection and thermistor motor protection make them an economical option, unlike standard frequency converters. There is also a simple adaptation for motor feeder provided in that model.
Sirius 3RW44 soft starters are used to work with three-phase asynchronous motors in:
- ventilation
- compression equipment
- equipping hydraulic systems
- transportation equipment
- elevators
- construction equipment
Ease of use is also among the strengths of the Sirius 3RW44 series. Equipped with four control keys and a text display, motor starters are easily configured for various operating conditions.
You can order starters and spare parts for them online in our store.
