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 1-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.
