Lightning and surge protection expert, DEHN Africa, has launched the coordinated type 1 DEHNbloc Maxi 1 CI 440 FM and DEHNbloc Maxi 1 CI 760 FM surge protective devices (SPD), specifically designed for higher system voltages, thus ensuring efficient protection against direct and indirect lightning currents in various industrial applications.
The devices require up to 60% less space than a conventional solution with an external backup fuse. In addition, the user does not have to be concerned about the correct dimensioning of the backup fuse as it is already integrated in the device, and is therefore adapted to the performance parameters of the surge protection components of the type 1 SPD.
The impulse-current-resistant fuse is optimised for discharging lightning currents of 10/350 μs wave form. Within the device, a spark gap is used which has a high mains follow current extinguishing capability in case of higher system voltages up to 760 V a.c. Thus, power-frequency follow currents are significantly limited and extinguished within a few milliseconds.
The operating-current-free status / fault indication of DEHNbloc Maxi 1 CI also monitors the integrated backup fuse and indicates its status.
