Time-delay, dual-element design delivers extended protection during transient surges while limiting damage from brief overcurrents. This reduces nuisance trips in motors and high-inertia loads, lowering maintenance costs and downtime in industrial panels and machine control applications. The 40 A rating paired with a 200 kAIC interrupt rating at 600 Vac provides robust circuit protection for high-energy lines, enabling safer shutdowns and easier fault isolation in assembly lines and processing equipment. Ferrule-end connections simplify installation with standard wiring practices, boosting installation speed while reducing wiring errors in control cabinets. The optional fuse indicator enhances maintenance efficiency by signaling when replacement is due, which minimizes unscheduled outages and helps technicians plan corrective actions. CE Marking and RK5 class certification support regulatory compliance and selective coordination across multiple zones in complex power distributions. With a compact 5.5 in length and a 1.6 in width, it fits a wide range of industrial panels without redesigns, and its Bussmann-series lineage aligns with existing protection strategies, delivering reliable, predictable protection for automation systems and legacy equipment.
