The LV NV/NH fuse-rails are 3-pole bases of LV fuse-links, intended for busbar mounting. They comprise three single-pole connections in one unit. Each contact at an individual phase is connected to the phase on the busbar system. The other contacts are fitted with cable connecting terminals or are intended for the attachment of the following busbar system.
The LV NV/NH fuse-rails are manufactured in compliance with the DIN 43623 standard. They are mostly used for installation into cable distribution cabinets and power supply systems. They are available in sizes of 00/160 A to 3/630 A. Covers provide insulation protection for all live parts.
The LV NV/NH fuse-rails are mainly used for cable distribution and power supply systems. They are intended for insertion of LV fuse-links that are inserted and removed from the fuse-rails by means of a special handle.
The insulated supporting body is made of polyester reinforced with glass fibres. A silver-plated contact system, fitted with tinned extinction chambers, ensures low power dissipation, optimum thermal characteristics, and a high breaking capacity.
All live parts are protected against accidental contacts in conformity with BVG A2.
All the LV NV/NH fuse-rails are fitted with new, modern Delta contact systems allowing optimum pressure contact between the fuse cartridge and the LV NV/NH fuse-rails, resulting in an extremely low level of power dissipation and heating-up.
All standard insulated LV NV/NH fuse-rails are intended for general usage. Appropriate individual configurations can be designed upon request.
