Technical Data 1048 Class R 2V and 600V modular ferrule and Knifeblade fuse blocks from 100 to 600 amps feature phase barriers between poles for additional safety with up to four mounting holes per pole increase installation flexibility. All knifeblade blocks meet UL creep and clearance requirements for Industrial Power Circuits (UL 8 and UL 845). Additionally, the 200 to 600 amp blocks meet the higher UL creep and clearance requirements for Power Distribution Standards (UL 8, UL 67, UL 48, UL 81 and UL 86A) All blocks have 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/tagout capability. These covers also have optional open fuse indication to speed troubleshooting. Easy circuit identification is available for 30 and 60 amp blocks and covers with universal marker labels. Catalog symbol: RM25_ (2V) RM60_ (600V) Description: Bussmann series Class R modular fuse blocks increase versatility, reduce labor and enhance safety for any panel or electrical system design. Available for the full Class R fuse amp range. These fuse blocks feature a standard fuse clip reinforcing spring for enhanced electrical contact between the block and fuse. All blocks are available as single-pole versions that snap together for the required number of poles, or as factory configured 2-, and 3-pole versions to meet stocking requirements. The modular design permits reducing inventory, assembly time and labor with tool-less assembly of multiple poles at point of use. Ferrule fuse blocks up to 60 amps save panel space with the smallest width dimension on the market and feature DIN-Rail and panel mount versatility so that one product can be used for multiple applications with lower inventory cost.
