DEHN DBM 1 440 (961 140) Coordinated single-pole lightning current arrester with high follow current limitation for UC = 440 V
The coordinated DEHNbloc Maxi 440 and 760 lightning current arresters are specifically designed for high system voltages.
This allows to efficiently protect a variety of industrial applications from direct and indirect lightning currents.
Be it in a wind turbine or a stand-alone low-voltage installation of an industrial enterprise, DEHNbloc Maxi devices exactly fulfil the specific requirements.
Both the design of the protective circuit and the enclosure specifically designed for this type of arrester are particularly adapted to high system voltages.
The approved RADAX Flow technology is the essential core element of the coordinated DEHNbloc Maxi 440 and 760 lightning current arresters.
Their capability of considerably limiting mains follow currents and extinguishing them within a few milliseconds makes these devices special.
The patented RADAX Flow follow current limitation ensures that low-value fuses are not tripped by follow currents.
The capability to discharge lightning currents without destruction and to suppress mains follow currents without tripping upstream overcurrent protective devices ensures a high degree of availability in electrical installations.
The operating state / fault indicator of the coordinated lightning current arresters needs no power to operate and immediately shows the operating state of the devices.
Apart from the standard visual indication with green and red indicator flags, DEHNbloc Maxi 1 ... FM features a three-pole remote signalling terminal.
With its floating changeover contact, the remote signal can be used as a break or make contact according to the particular circuit concept.
