NH Fuse-Rails – Sizes ½ – 3

Design B

NH fuse-rails, sizes ½ – 3 acc. to IEC/EN 60 269 – 2 – 1 design B are fully protected against direct contact with live parts acc. to BGV A3 by covers on feeder contacts. This protection against direct contact with live parts can be optimized by using additional fuse covers. Due to the tightly packed design it is not possible to touch the busbars between the unit. The feeder contact of the fully insulated version is always covered. NH fuserails sizes 1/2 – 3 are identical in form and dimensions. An interchangeability of the units is guaranteed. With the fully insulated hook (see accessories) the simple fixation onto the busbar is possible even under load.
