DEHNrail M from DEHN is a two-pole modular surge arrester for the protection of electronic equipment in industrial and commercial installations.
With its modular construction and combined base unit and plug-in modules, the system meets the requirements of the EN 61643-11 standard for class 3 surge protection devices.
DEHNrail M can handle a nominal discharge current (8/20 microseconds) of up to 5 kA, and offers a very low level of let-through energy and voltage protection when used in conjunction with the required class 2 arresters. The nominal load current is also increased by 40% to 25 A from the previously rated 16 A. DEHNrail M incorporates a two-pole device in a single 18 mm modular width.
With its Red/Line design, DEHNrail M is available with a floating changeover contact for remote signalling to control devices. A module release button allows for the easy exchange of the protection module.
