Low voltage general purpose fuse with time delay feature. Optional solid-state SmartSpot indicator. Time-delay feature for motor start-ups and transformer inrush currents without nuisance opening. Current-limiting for low peak let-thru current. Rejection-style design prevents replacement errors (when used with recommended fuse block). This fuse is used with motor circuits, mains, feeders, branch circuits, transformers, service entrance equipment and general-purpose equipment.
