UL Supplemental (Midget) Fuses
Primary current-limiting and overcurrent protection devices gain in reliability when supplemented by backup devices. Enter 10x38 mm fuses to bolster the performance of industrial UL fuses. Littelfuse makes fast-acting and time-delayed 10x38 mm fuses for panels, small motors, and meters. Several incorporate POWR-GARD® technology, and some feature indicator pins that pop up when fuses blow. Another line of semiconductor fuses is available for other applications.
