Description
DEHNbloc Maxi DBM 1 440 FM
The DEHNbloc Maxi DBM 1 440 FM is a single-pole Type 1 arrester that reliably protects your electrical installations against direct lightning currents. Thanks to RADAX Flow technology, the device effectively limits post-lightning currents and prevents fuses from tripping. It is particularly suitable for applications with high short-circuit currents of up to 100 kA. The compact design, the green/red status indicator and the FM changeover contact make integration into your protection concept particularly straightforward.
