3TK Contactors

SIRIUS has long been synonymous world-wide for industrial controls and was a trendsetter in this field from the very beginning. The SIRIUS modular system with its components for the switching, starting, protection and monitoring of motors and industrial systems stands for the fast, flexible and space-saving construction of control cabinets.

The SIRIUS modular system in sizes S00 to S3 up to 55 kW/400 V (AC-3: 110 A) has been completely revised with respect to both the main and the control circuits. As a result, the innovative basic components such as motor starter protectors and contactors provide a host of advantages to optimize your plant, today and in the future. Often the innovation is to be found in the details. For example, more power in the same design and the bundling of functions in basic units for notable space savings.

Another aspect at the focus of the new developments was the enhancement of plant availability. In future, SIRIUS components from the modular system can even be used at minimum expense to monitor the application. Selective plant monitoring then becomes utterly simple – with current monitoring relays integrated directly in the load feeder or configured from the controller via the load feeder connection to AS‑Interface or IO‑Link.
