Imagine a perfectly planned electrical installation, preferably fully digital, in 3D and harmonised with the other trades in the building. Everything is ready, it just has to be installed.
This is what the brave new world of building design should look like. But the day to day reality on the construction site is far from this vision. Of course, proper planning is important, but all too often one thing is needed above all else: Flexibility.
Making life easier for you as an electrician has always been the guiding principle of our development work. Our new flexible cable junction boxes for explosion-protected areas have also been developed with this in mind. They transfer the advantages of the well-known HENSEL box to this demanding application. In order to do justice to this sensitive environment, we offer the product as a system solution including the matching cable glands. This guarantees you and your
customer the highest degree of safety.
But as always: see for yourself! The products are available immediately.

installations in potentially explosive atmospheres, or Ex zones for short,
require specially tested products in accordance with European Directive
2014/34/EU. Electrical specialists must select suitable equipment taking the
operational environment into account.
It goes without saying that this equipment must meet the necessary quality requirements for Ex zones.
At the same time,
however, it can also be used flexibly and be adapted to the many challenges
present on construction sites.
With modern terminal technology and variable cable entry, it is possible to meet multiple on-site requirements using just a few versions of the product.
KX Series cable junction boxes with flexible product features adapt to the diverse, changing requirements on site.
As well as being suitable for Ex zones, the operational conditions of use, actual requirements and influences on the equipment must be taken into account. Approx. 80% of all electrical installations in Ex zones are within Zone 2 or 22. Here, construction sites can present a challenge, whether due to other installations or because the site owner changes things at short notice. If a cable junction box cannot be adjusted flexibly on site, for example if more cables need to enter and be terminated than originally planned, it can be a complex process to find and procure an alternative. This costs time and money.
Equipment in potentially explosive atmospheres must be procured and operated in such a way that no potential ignition hazards arise in operational conditions, for example by:
- Avoiding electrostatic charge
- Limiting surface temperatures
- Protecting against ingress of flammable and/or conductive dusts
Installation example 1:
Spontaneous order extension - an additional socket must be connected. Now more cable entries are needed in the enclosure. The pre-installed screw fittings are not sufficient.
Installation example 2:
More cables have to be inserted and connected per pole than planned. There is a lack of space at the terminal.
Can be easily adapted to new installation situations on site
allows plenty of space for wiring
