THE problems are well known when it comes to fitting cable assemblies of different thickness and/or with plugs in enclosures.
To compound matters, protection category used by the enclosure must always be maintained during industrial use.
The new bus housing from Rittal , which has modular plates for individual cable entry, provides the solution.
The housing has pre-installed top hat rails for taking the de-centralised peripheral system, such as motor starters and input / output modules. The two rows offer sufficient room for even the largest motor starters. The door, which has an viewing window made of Macrolon, enables visual checking of the LED signals to be carried out.
The housing which is an especially attractive economical alternative when combined with modular peripheral systems using protection category IP20; you no longer have to use the considerably more expensive modules using protection category IP65 or IP67.
There is another advantage in addition to this, service personnel will keep their fingers clean in the true sense of the word: all adjustment and service work is carried out on the protected components fitted inside the housing.
Space can always be reserved in the housing for future electrical modifications now, which means that they do not have to be built in later on by your colleges using mechanical components.
The base of the housing has 18 individual cable entries, which are closed off by modularly designed flange plates. There are six versions available for use. Four are made of zinc-plated and chrome-plated steel plates: with plug inlets for two cables up to 8.5 mm in diameter and closed for their own configuration, with holes punched for M 25 or M 32 metric cable screws.
In addition to these there are two other versions made from synthetic material with strain relief and flexible sealing membranes (including stops for openings that are not being used) for direct, IP protected installation of sensor/actuator lines.
