The installed surge arrester provide a combination of safety and innovation. The arresters integrate lightning equipotential bonding and surge protection in a single device, making them ideal for use in compact electrical installations.
The energy-coordinated arresters even allow to protect terminal equipment if the distance between surge arrester and the loads is ≤ 5 m or 15 feed.
With a lightning current discharge capacity up to 100,000 A, the arresters ensure a high degree of availability of the electrical installation to be protected.
Even in large-scale electrical installations, the modular surge arrester arresters provide various application benefits.
The surge arresters installed at the boundaries of the individual lightning protection zones. A special feature of the modular surge arresters is its functional design, in particular the module locking system. It fixes the protection module firmly in place so that it is safely connected to the base part even with maximum loads. Protection modules can be easily replaced without tools by pressing the module release button and removing the protection module.
The patented RADAX Flow technology ensures follow current limitation and extinction as well as maximum system availability of the electrical consumer's installation to be protected.
Even in case of short-circuit currents as high as 100 kArms, mains follow currents are reduced in such a way that selectivity with respect to low-value fuses is ensured,
meaning that upstream fuses are not tripped by mains follow currents.
The operating state / fault indicator of each protective path needs no power to operate and immediately shows the operating state of the surge arrester. Apart from the standard visual indication with green and red flags
