Class R modular fuse blocks enhance safety for any panel or electrical system design and are available for the full Class R fuse amp range. All blocks are available as snap-together single-pole versions for toolless assembly of multiple poles at point of use; or as factory configured 2-poles; and 3-poles versions to meet stocking requirements. All blocks are equipped with a fuse clip reinforcing spring to minimize temperature rise while maintaining reliable surface contact between the fuse and clip over the blocks service life.
100A to 600A knifeblade fuse blocks feature phase barriers between poles for additional safety with up to four mounting holes per pole to increase installation flexibility. All knifeblade blocks meet UL creep and clearance requirements for Industrial Power Circuits (UL 508 and UL 845); with the 200A to 600A blocks meeting the higher UL creep and clearance requirements for Power Distribution Standards (UL 98; UL 67; UL 489; UL 891 and UL 869A). All blocks are available with optional IP20 finger-safe high clarity; see-through covers for inspecting wire terminations or thermography measurements without removal. All covers enhance safety by featuring probe holes for easier; safer testing and a lockout/tag-out capability. These covers also have optional open fuse indication to speed troubleshooting. Easy circuit identification is available for 30A and 60A blocks and covers with universal marker labels.
