These fuses avoid needless blows from starting currents or surges. They have a fuse link which operates only on very high overloads or short-circuits. They have a thermal cutout which functions on low overloads. The thermal cutout cannot operate quickly at any load, hence long time-lag is obtained. Yet protection is afforded against short-circuits or continued overloads. Test specification - carry 110%, open at 135% within 1 hour. MDL 0 to 2 8/10amperes and MDX 0 to 7 amperes listed by Underwriters' Laboratories, Inc. MDL fuses have longer time-lag than MDX fuses.
