Everything. Systematically. SIRIUS modular system. Building control cabinets must be fast, simple, flexible and space-saving. How can all this be achieved? With the unique SIRIUS modular system that offers everything you will need for switching, protecting, and starting motors and systems. In other words, it provides a modular range of standard components up to 250 kW/ 400 V in only seven sizes, which are perfectly matched to one another, can be combined really easily, and largely use the same accessories. That’s how easy industrial controls can be! Continuous further development and...

With its wide range of components, the SIRIUS modular system features the most diverse functions for use in the control cabinet, and offers a host of benefits in assembly and handling, in application monitoring, and also in controller interfacing, or when planning and configuring. Assembly and handling: Error prevention and reduced wiring effort - with maximum flexibility • Load feeders: easy to implement up to 250 kW/400 V from standard devices • Modular design: everything fits together and can be combined • Variants and sizes: economical and flexible thanks to 7 compact sizes •...

Much more than ON/OFF: SIRIUS 3RV motor starter protectors The SIRIUS 3RV motor starter protectors are compact, current-limiting motor starter protectors. They ensure secure disconnection in case of a short circuit, and they protect consumers and the system against overload. They are also suited to normal switching duties for loads with a low switching frequency, and for safely isolating the system from the power supply during maintenance work or modifications. For applications over 100 A, SENTRON 3VA and 3VL circuit breakers are suitable. Rugged and reliable: SIRIUS 3RT contactors Thanks...

Efficient and flexible power distribution The components of the SIRIUS modular system can be wired extremely flexibly. For sizes S00 and S0, the simplest method is to connect the components via the associated SIRIUS 3RV29 infeed system in each case. Alongside this, the 3RA68 infeed system is available in conjunction with the 3RA6 compact starter - and both connection methods are available optionally for devices with screw and spring-loaded terminals. Individual motor starter protectors, complete load feeders, and compact starters are just clicked into the infeed systems. An entire feeder...
