Switching is a Question of Technology

Thursday, March 29, 2012

Industrial controls have proven a millionfold in all sectors. While the term mainly referred to devices with rather simple operating principles such as mechanical contactors or switches in the past, this technology is meanwhile subjected to way greater expectations.

The new Sirius modular system is now completely available with spring-loaded connection system, which meets the request for accelerated and safe installation. Besides simple plug connections, this technology offers further benefits such as a particularly vibration-resistant connection and the optional elimination of end sleeves.

An extreme performance increase represents a further important argument for conversion to the new generation of industrial controls. Size S00 now covers a power range up to 7.5 kW, size S0 even up to 18.5 kW with 400 V. This facilitates the use of smaller contactors and contactor combinations in many applications, which results in significant advantages in terms of space requirements and investment costs.

For a particularly compact feeder arrangement, the Sirius Innovations range comprises corresponding infeed systems 3RV29 and 3RA68 – of course either with screw-type or spring-loaded connection system. For users, this results in considerably eased wiring and minimized wiring faults.

As a further highlight of SIRIUS Innovations, all devices can be interconnected by means of plug-in technology. For example, plug-in connecting modules are available for the permanent interconnection of contactor and circuit breaker for motor protection. Also the current monitoring relays and overload relays are simply plugged onto the contactor via the bottom. The devices' control circuit connection is realized by means of function modules which are plugged into the devices via the front with the flick of a wrist.

Thanks to the new generation of the Sirius modular system, complete feeders can be integrated in the control architecture. Corresponding function modules with interfaces to AS-Interface and IO-Link are available for mounting on 3RT contactors. This supports the easy diagnostics of direct-on-line, reversing and star-delta starters.
