SLIMLINE MOTOR CONTROLLERS CREATE SPACE IN ENCLOSURES S mall drives for machines and equipment are typically powered 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 find room for significant numbers of protective components. Rittal’s new motor controllers for its RiLine Compact power distribution system offers a sophisticated solution. To assist the engineer Rittal has also produced a 3D configurator that reduces the time required to generate Compact RiLine busbar systems. Following the successful launch of the busbar system “RiLine Compact” at the beginning of the year, Rittal is now expanding the product range. Until now, the small 125-A-max busbar system consisted entirely of shock- hazard-protected boards, which form the basis 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 other manufacturers. Rittal will shortly be launching new motor controllers into the range. These can be fitted directly and easily onto the board in a one-step installation, to minimise 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. These combine the functions of direct starter and reversing starter within one single device.
