What fire-rated enclosure options are available and how do they simplify installation?

For fire-rated installations we offer our Lifeline WKE 2-6 range, which pairs intrinsic fire resistance with features built to simplify the installation itself. Durability and heat resistance are only part of the story. They are essential qualities, especially when you are dealing with systems that need to stay operational for 30, 60, 90 or even 120 minutes into a fire, but most installers also need flexibility. Every install is different, and the enclosure has to adapt to the real-world layout of the electrical system.

The Lifeline WKE 2-6 range lives up to the motto for this series, “be flexible”. The features that make the difference on site are:

• An adjustable mounting rail that can be set in two different height positions, giving room for single or double terminals as well as fuse holders. If you are working with D0 (NEOZED) fuses, the lower position is ideal, while the upper position keeps standard terminal blocks perfectly aligned. It is a small detail, but it counts when you are trying to keep an install efficient and tidy.

• A base carrier that can be repositioned in 45-degree steps with just one screw, so the terminal block can be angled exactly as required. In tight spaces or with awkward cable runs, that adjustability saves a lot of time and frustration.

• External fixing lugs that come pre-fitted and can be rotated through 90 degrees, so the enclosure can be mounted securely in no time, even when the surface or orientation is not perfect.

• Patented knock-out membranes that make cable entry clean and quick, with no cracking and no rough edges, just smooth insertion that keeps the job moving.

All of this flexibility sits on top of the core strength of the WKE series: reliable intrinsic fire resistance. The boxes are made from high-performance polycarbonate that stays non-conductive in a fire, so you do not get short circuits at the moment the system needs to perform at its best.

Whether the application is emergency lighting, alarm systems or pressure boosting systems, the WKE range helps make sure critical infrastructure keeps working precisely when it matters most.
