Protection of bus duct with current-limiting fuses

METHODS FOR PROVIDING the best possible short-circuit protection of busway systems continue to be of prime importance to users and manufacturers of this equipment. The importance of preventing fault-current damage to the busway system arises from the necessity of protecting plant personnel, the high replacement cost of the equipment itself, and the financial and productive losses occurring through the forced inactivity of large sections of the industrial plant. The current-limiting fuse has been investigated and found that it contributes significantly to the improvement of short-circuit protection of busways and associated equipment.
