DEHNpipe MD Ex (i)
Surge arrester
Surge arrester for outdoor use to be screwed onto two-wire field devices.
Stainless steel, installation up to a degree of protection of IP 67.
DEHNpipe is made of corrosion-resistant stainless steel and is screwed
onto the field device instead of the conventional cable gland. The permanently
connected lines are then connected to the terminals of the field
device. Thus, the protective components are directly situated in the cable
run, allowing energy-coordinated surge protection. The arrester protects
the inside of the field device against dangerous surges with the interfering
impulses being discharged via the metal enclosure only and not via
the inside of the field device. DEHNpipe MD Ex (i) can be either used in
Ex zone 1 or 2.
