Special features
Knife blade
Knife blade design enables fast, tool-free fuse changes, reducing maintenance windows and downtime for high-demand lines. The 70 A rating paired with a 10 kAIC interrupt rating minimizes fault energy, protecting downstream equipment from damaging arcs and preventing outages that ripple through a line. This makes the KOS70 well-suited for motor feeders, control panels, and power distribution blocks in conveyors, packaging, and process industries where uptime directly drives productivity. 600 V operation ensures reliable protection across common automation cabinets and drive circuits, enabling designers to co-locate fuses with controllers without over-stressing wiring. Class K5 construction delivers predictable operating characteristics, improving coordination with upstream devices and reducing nuisance trips. The non-indicating status minimizes panel clutter in bright environments, while standard packaging of five pieces supports batch procurement and inventory control for assembly lines. Installation and compatibility considerations help streamline field service. The 7 in length and 1 in width/height footprint fit standard fuse racks and panel boards, while the knife blade contacts promote secure seating and quick, confident removal during maintenance. For designers migrating from legacy Bussmann or Edison catalogs, the KOS70 catalog number offers straightforward cross-referencing and a smooth supply chain transition. Compliance and safety alignment informs robust engineering decisions. CE Marked status communicates conformity with European safety directives, while CSA Certified status supports North American regulatory expectations. The fuse's 70 A rating at 600 V aligns with protection schemes for industrial controls and drives, enabling auditable documentation and easier vendor qualification during OEM projects. Operational efficiency and lifecycle value emerge from practical design choices. Knife blade replacement reduces service time, while a five-pack packaging strategy lowers stocking costs and improves reorder accuracy for maintenance teams. In regulated environments, the combination of Class K5 performance and 10 kAIC interrupt capability supports safe, compliant operation across legacy systems and modern automation architectures.
