POWR-BAR Busbar

Safe distribution of power to multiple fuse holders in a compact design is a key objective for panel designers. The Littelfuse UL508 bus bar system eliminates most wire terminations in a timesaving package. A power distribution block and associated conductors are no longer needed to feed multiple POWR-SAFE fuse holders.
