Small drives for machines and equipment often lie in the range of up to 9.0 A and are protected by conventional motor circuit breakers. However, when space in the enclosure is limited, it is very difficult to accommodate a high number of protection elements. With the new motor controllers for its RiLine Compact power distribution system, Rittal is now able to offer a sophisticated solution using new technology that is far from ordinary.

Following the successful launch of the new busbar system "RiLine Compact" at the beginning of the year, Rittal is now expanding its RiLine Compact portfolio even further to include additional components. Until now, the small 125-A-max busbar system consisted entirely of shock-hazard-protected boards, which form the basic element of the system along with assembly components such as connection adapters for busbar infeed and component adapters for the easy set-up of switchgear and protection devices produced by different manufacturers. To expand its product portfolio, Rittal is launching new motor controllers. Just like the existing components, these units can be fitted directly and easily onto the board, connecting mechanically and electronically in a one-step installation. The simple device installation, as well as the internal circuit and wiring, greatly minimises the time and effort spent on wiring.

A compact solution for small spaces

Rittal offers motor controllers in three staggered current ranges: 8 A/2.4 A/8 A. They perform the functions of direct starter and reversing starter in one single device. At only 22.5 mm wide, the extremely slimline design is particularly impressive. It means freeing up around 50% more space compared to the standard 45 mm switching device in this current range and as much as 75% more space compared to the 90 mm-wide reversing combinations.

Hybrid technology to impress

The three-phase motor controller is a high-performance hybrid switching device with a current monitoring function. With its hybrid technology, the device offers a longer lifespan and low-loss operation. The principle behind it is simple: First, the electronics are switched on via the input signal, and then the mechanical contacts take over for the main duration. The motor controller offers even more advantages with its diagnostic function, which it uses to detect internal and external errors. The operating statuses and error messages can then be evaluated through the four different illuminated LEDs.
