70/30 brass end cap
Non-indicating, 70 A LENRK70 fuses reduce panel indicators while delivering consistent protection; this minimizes maintenance overhead and simplifies replacement planning, contributing to uptime gains in critical lines. The device supports high in-rush current protection with a 200 kAIC interrupt rating, enabling rapid fault clearance in motor starters and drives, which lowers arc-flash exposure risk and conductor damage. Class RK1 recognition ensures compatibility with standard Edison fuse holders and motor control centers, while the 5-pack packaging streamlines stocking and eliminates last-minute outages on the production floor. Electrically isolated end caps with 70/30 brass construction provide safe, dependable terminations, reducing installer torque requirements and improving field reliability across HVAC, conveyors, and pumps. Compliance features—RoHS, UL Listed, and CSA Certified—bolster regulatory alignment and supplier quality for harsh industrial environments. The LENRK70 footprint (5.88 in L, 1.1 in W, 1.1 in H) supports common panel designs, enabling straightforward retrofits and upgrades without changing enclosure layouts.
