NH fuse bases made of plastic are available in single-pole and three-pole versions. They can be mounted close together. Two phase separators are included with each three-pole base. NH clip-on covers for clipping onto the contact springs are also available. Additional connecting elements make it possible to place separators between any number of bases in a row. These connecting elements and separators must be ordered separately if required. Bases of size 00 can be connected without connecting elements. Depending on the design, bases of sizes 00 to 3 have a one-piece plastic base for snap-on mounting on a mounting rail or screw mounting on a mounting plate. Size 4 has a metal base plate with 2 ceramic bases. The stable silver-plated contact springs are made of electrolytic copper and are formed from one piece. Separate suspension is achieved by highly elastic, captive steel springs, which make the contact insensitive to high thermal loads. NH sockets size 4 are designed for NH-4 fuse links with 8mm wide screw lug contact. A micro switch can be used for NH fuse links with firing pins.
