Littelfuse RLN040 40A 250V Class H Renewable Fuse

Littelfuse RLN040 combines a 40A rating and 250V AC capability with renewable fuse behavior. Its cartridge / clip form factor, Class H size and 10kA AC rating define the core installation limits. Applications include feeder circuits, branch circuit protection and general purpose; verify installation requirements against UL 248-6 and the listed UL Listed and CSA approvals. For renewable Class H designs, Littelfuse advises against new applications, so use the datasheet to confirm available fault current and replacement-link requirements.
