The LENRK125I fuse delivers a 200 kAIC interrupt rating, enabling safe interruption of motor faults during startup surges and reducing arc flash risk in heavy-duty drives. This translates to lower downtime and higher equipment availability across production lines. With a 125 A rating and dual voltage capability (250 VAC and 125 VDC), it supports diverse motor circuits, simplifying panel design and procurement while protecting critical loads such as conveyors, pumps, and fans. The 70/30 brass end caps paired with electrically isolated end caps provide reliable, low-resistance contacts and safer maintenance in harsh industrial environments, extending fuse life and reducing maintenance costs. The non-indicating design minimizes labeling complexity in dense control panels, while standard packaging and Edison LENRK compatibility streamline stocking and field replacement. Certifications CSA Certified UL Listed affirm compliance and risk mitigation in regulated facilities.
