KDS-RAIL Fire Protection Kits
Cable entries for applications in railway technology
In modern rail transport, cable management systems must not only be reliable, but also safe and flexible in use. Our cable entry and cable management solutions are tested and certified in accordance with the requirements of DIN EN 45545 (E30).
For particularly stringent fire protection requirements, KDS-RAIL systems are available featuring plastics of the highest hazard class, HL3. They thus offer reliable protection whilst providing a wide range of options for routing, feeding through and organising a wide variety of cables and wires.
CONTA-CLIP’s cable management systems can be flexibly adapted to the specific requirements of each rail vehicle.

RAIL sealing elements made from railway-approved material for KDS cable entry systems
The KDS-DE-RAIL (small) and KDS-DEG-RAIL (large) sealing elements form the core of our railway-certified cable entries. Manufactured from a special TPE approved in accordance with DIN EN 45545-2 (HL3), they guarantee the highest levels of safety, fire protection and reliability for demanding applications in rail vehicles.
The conical shape of the sealing elements allows them to be easily pressed into the openings of the cable entry systems without the need for tools. At the same time, it ensures an absolutely reliable seal of the gaps and static strain relief in accordance with DIN EN 62444. The clever corrugated cut of the split sealing elements guarantees an extremely easy-to-fit and precise-fitting sheathing of the cables, even for pre-assembled connectors.

Solutions for the connection level of transformers
As components, transformers have a significant impact on the functionality of technical processes and are primarily used in applications to adjust voltage levels.
However, their use also enables the creation of new power configurations. Downstream systems can be permanently designed for the same power configuration and voltage with the help of transformers, regardless of where in the world they are put into operation.
Since installation conditions are often challenging in these scenarios and there are also high electrical requirements at the connection level, CONTA-CLIP stands out as THE specialist for the connection level with its extensive range of transformer terminals.
You decide whether the transformer terminals are equipped with the proven screw-terminal system or the innovative and patented push-in connection system. Discover the extensive portfolio of transformer terminals, terminal blocks, and bolt terminals for connecting transformers with aluminum and copper conductors ranging from 0.2 mm² to 300 mm²
Product features: innovative – safe – reliable.
