MERSEN NH fuse gG size 000 400VAC 20A with live grip lugs DKM

The NH system is classified as a plug-in fuse system and is made up of the following: fuse base (possibly with connection covers and phase cover), fuse inserts with contact blades, device for replacing the fuse inserts (low-voltage plug-in handle). Maintenance and servicing must be carried out by qualified personnel. NH fuse inserts of operating class gG are used to protect cables, devices and systems. They safely switch off impermissible overcurrents and short-circuit currents up to the rated breaking current. Fuse inserts gG also protect electrical devices and systems from the electrodynamic effects of high short-circuit currents. The rated power output values ​​of the Mersen NH fuse inserts AC 400V are lower than the maximum values ​​according to the standard IEC 60269-1 and -2, VDE 0636 Part 201.
