When planning the new swimming pool, Klaus Bastian’s focus was on securing the power supply so that bathers will be able to relax and enjoy an undisturbed bathing experience.

What drew your attention to arc fault protection initially?

Klaus Bastian: As a planning engineer, I have to ask myself “What does my customer want?” and offer appropriate advice. I was already aware of the fact that arc fault protection plays an important role in terms of system availability and personal protection. I took advantage of the chance to visit the DEHN stand at the Light & Building 2016 exhibition and found out more about the DEHNshort arc fault protection system.

How did you argue the case for DEHNshort with your customer?

KB: Availability is the number one priority at a public swimming pool like the Freizeitbad Stegermatt because it is in operation around the clock. A power failure due to a short circuit could put the pool out of action for up to 4 weeks – after years of planning and building. This would be difficult to explain to the general public and severely damage the image of the operator. So, it was easy to convince the technical operations department in Offenburg of the need for an arc fault protection system in terms of reliability.

How much did the arc fault protection system cost?

KB: The costs in euros lie somewhere in the lower five-digit region. This is a negligible amount seen in relation to the total investment costs. We are talking here about an investment in the main distribution board with an estimated service life of 40 years. This important “life vein” for the swimming pool has now been protected against failure with DEHNshort.
