Littelfuse® POWR-GARD® LKN300 LKN Fuse Link, 300 A, For Use With RLN Series Class H Single Element Renewable/Time Delay Fuse
The LKN Series are fuse links designed for Littelfuse RLN series renewable fuses. Traditionally, Class H fuses were used to provide low cost protection of general purpose feeder and branch circuits where available short-circuit currents did not exceed 10,000 amperes. However, generally increased levels of available fault current and the distinct possibility that renewable fuses may be improperly renewed, rendering them unsafe, have all but eliminated the use of these fuses in new applications. In addition, escalating labour costs and increasing automation, which makes downtime very expensive, have greatly reduced or eliminated the cost savings attributed to renewable fuses.

Sealmaster® gold mounted ball bearings feature a wide outer race insert bearing with land riding metallic retainer. The black oxide treated bearing steel insert features an exclusive lock pin and dimple system providing a direct path for lubrication into the bearing and prevents outer ring rotation within the housing. Shaft lock is achieved by either setscrew or Skwezloc® concentric locking collar. The felt seal with flinger provide a good balance between contaminant entry, GoldPlex® HP grease loss and friction.
