Current limiting - reduces short circuit damage to systems and equipment and reduced downtimeEasily coordinated with other system componentsTen second minimum time delay at 500 percent of rating eliminates needless downtime caused by heavy starting currents of large motors and other inductive loadsSelective coordination - KLLU fuses coordinate well with other class L fuses and with all current-limiting Littelfuse® fuses rated 600 A or lessReduced downtimeKLLU fuse time-current characteristics closely match typical time-current curves of circuit breakersAlthough fuse/circuit breaker systems can seldom be 100 percent coordinated , KLLU series fuses permit use of a wider range of breaker setting than fast-acting class L fusesExcellent protection for a single breaker or a group of breakers200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating
