DEHNpipe CD Ex (i)
Surge arrester
SPDs for Use in Potentially Explosive Atmospheres
• Surge protective device for field devices with
spare cable gland
• Easy to retrofit and extremely space-saving
• ATEX, FISCO, IECEx approval
Surge arrester for outdoor use to be screwed onto two-wire field devices.
Stainless steel, installation up to a degree of protection IP 67.
DEHNpipe C is made of corrosion-resistant stainless steel and is screwed
directly onto the field device. Like a field cable, the permanently connected
lines are connected to the terminals of the field device. Thus, the protective
components are situated in parallel to the cable run. DEHNpipe C
can be easily connected to metal or plastic enclosures as the earth wire
of the protective device can be connected to the earth terminal of a field
device.
The design of the surge arrester allows a degree of protection IP 67.
Intrinsically safe surge arresters are typically used in 4-20 mA measuring
circuits or bus systems up to 30 V. Depending on the type used,
DEHNpipe C is designed for measuring sensors with M20 x 1.5 or 1/2-14
NPT cable gland connections and can be either installed in Ex zones 1
or 2.
