Dear Paulo,

Thank you for your interesting enquiry.

At Spelsberg, we know how important it is to ensure safety in the event of a fire by enabling critical systems to continue operation. This means creating enclosures that can withstand high temperatures without allowing the fire to spread, while maintaining the integrity of the electrical components inside. In this way, we strive to ensure that essential services remain operational during a fire, helping to secure evacuation routes and emergency responses.

This is why we have developed solutions that meet key fire safety standards, particularly DIN 4102 part 12. Our work with customers in the railway sector has enabled us to understand and align with this pivotal safety standard in a meaningful way.

Let me introduce you to our WKE Rapid-Box range of enclosures for tunnel applications. These embody our commitment to safety and innovation. They have been precision engineered with temperature-resistant ceramic terminals and include uncut conductors of up to 50 mm² (Cu). In addition, the safe junction takes place with a 2.5 mm² conductor or via CEE socket (3-pin or 5-pin) in the housing cover.

The WKE Rapid-Box cable junctions and connection housings are also certified according to EN 61439:2011 and ensure intrinsic fire resistance in the passage for 30 minutes. Additionally, with a minimum of IP66 rating, they offer unmatched protection against challenging conditions.

You can also read how our enclosures were used in the ‘Kanzlerbahn’ project in Berlin, providing reliable fire protection solutions under rigorous conditions: https://www.spelsberg.co.uk/solutions/electrical-functional-integrity/case-studies/berlin-underground-line-55/

If you have any additional requirements for your intended tunnel application, please feel free to send me a private message. I’d be happy to discuss with you the specific needs that your enclosure needs to meet.

Kind Regards,
