Eaton LESRK150 Fuse - UL Listed RK1 Motor Protection

Non-indicating design with electrically isolated end caps enhances service safety and reduces misreads during maintenance. In crowded panels, technicians can replace fuses quickly without concern for indicator states, minimizing downtime and human error. This feature is particularly valuable in automated lines, pumps, and fans where space is tight and rapid response to faults is critical. The design also simplifies retrofits by enabling straightforward stocking without scouting for indicator variants. High inrush protection and robust interrupt rating deliver real-world reliability. The LESRK150 is rated at 150 A and 600 V with a 200 kAIC interrupt capacity, enabling safe operation of high-inertia motors and soft starters. By containing startup surges and isolating faults, it protects drive electronics and reduces collateral damage to cables, contactors, and nearby equipment. Class RK1 and standard packaging simplify procurement and installation. This fuse is designed to work with Edison Bussmann style accessories and standard fuse blocks, helping technicians avoid mismatches. At 9.63 in long and 1.61 in wide, the compact form factor fits common panel spaces while maintaining easy access for inspection and replacement. Certifications and risk reduction: CSA Certified and UL Listed provide clear compliance signals for global supply chains. The combination of approvals supports quality programs and reduces qualification cycles for new equipment. In practice, you gain predictable protection, improved uptime, and a clearer path to regulatory conformance when specifying LESRK150 in motor protection schemes. Industry relevance and practical notes: This fuse is designed for high inrush motors often used in HVAC and material handling; for best results, pair with appropriate upstream protection and fusing schemes.
