Bussmann LPS-RK-400SP Fuse

Bussmann LPS-RK-400SP is a high-current, low-peak dual-element time-delay fuse from Eaton's Bussmann LPS-RK family designed for Class RK1 protection of large-load circuits. Rated for 400 A and capable of withstanding up to 600 Vac (300 Vdc), this blade-end, non-indicating fuse combines time-delay operation with current-limiting performance to handle inrush events while providing fast fault clearance. It features interrupt ratings of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, ensuring robust protection in demanding equipment and power-distribution setups. The unit measures 11.63 inches in length, 2.36 inches in height, and 2.36 inches in width, and weighs about 4.6 pounds, with electrically isolated end caps to ease safe installation in panels. It is RoHS compliant and CE marked, reflecting compatibility with global environmental and safety standards. Catalog number LPS-RK-400SP, this low-peak RK1 fuse is well-suited for protecting heavy-load circuits in industrial facilities, motor drives, and power cabinets where high-current protection at 600 Vac is required and where a long, slim, blade-terminal form factor is advantageous.
