3RW44 for High-Feature Applications

Thanks to its outstanding functions, the SIRIUS 3RW44 all-round talent handles difficult start-up and deceleration processes in a simple and, above all, gentle manner. With its innovative torque control system, it can be used for drives with a power output up to 710 kW at 400 V – respectively 950 hp at 460 V – in an inline circuit or up to 1200 kW at 400 V – respectively 1700 hp at 460 V – in an inside-delta circuit. Designed for simple handling, the functions are exceptionally easy to use.

Advantages at a glance
Optimum acceleration due to torque control
Simple and fast commissioning thanks to user-friendly display
Savings in size and costs due to optional inside-delta circuit
Simple integration in higher-level control units via PROFIBUS

K-Drives has established itself primarily as an important, globally oriented B2B supplier, specialized in perfect solutions for large-volume and long-term orders.
To free up our capacity for what we do best, we are leaving the area of retail and B2C sales.

To the thousands of our retail customers who have been buying from us during 30 years of our history, we thank them for their trust and support.

Thanks to this step, we will bring larger B2B and project customers from all over the world even better service in the technical and commercial spheres, the most modern methods of communication and data exchange, and a more individual approach.

Our popular configurator remains in operation, but the webshop changes to a platform for entering requests (it is no longer possible to buy directly online).

Thank you for your understanding.
