Slimline motor controllers create space in enclosures

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.

Rittal offers motor controllers in three staggered current ranges: 8A/2.4A/8A. These combine the functions of direct starter and reversing starter within one single device.

A slimline profile - just 22.5mm wide frees up about 50% more space compared to the standard 45mm-wide switching device in the range, and as much as 75% more space compared to the 90mm-wide reversing combinations.

The three-phase motor controller is a high-performance hybrid switching device with a current monitoring function, offering a longer lifespan and low-loss operation. The principle behind it is simple: first, the electronics are switched on using the input signal, and then the mechanical contacts takeover for the duration.

The motor controller also provides diagnostics, which to detect internal and external errors. The operating statuses and error messages can then be evaluated through the four different illuminated LEDs.

To help engineers, Rittal has also produced a 3D configurator that reduces the time required to generate Compact RiLine busbar systems.
