DiversiTech Fuse 80A 250V Class K5 1 NLN080

The DiversiTech NLN080 is an 80 amp, 250 volt Class K5 fuse for feeder and branch circuit protection in commercial and industrial electrical distribution.

Class K5 designates a fuse with defined interrupting and current-limiting characteristics suited to applications where available fault current is moderate and the equipment listing permits this class. It offers a practical balance of protection and cost for distribution work that does not demand the tighter let-through performance of Class RK1 or Class J fuses.

The 250 volt rating covers single phase 120/240 volt systems and three phase 240 volt delta systems common in light commercial and industrial facilities. At 80 amps, the fuse suits feeders to subpanels, larger motor branch circuits, and HVAC and refrigeration equipment with substantial connected load.

Applications include fused safety switches and disconnects serving mechanical equipment, panelboard and switchboard protection, motor branch circuit protection, condensing unit and rooftop equipment feeders, and general commercial distribution.

Selecting the correct fuse class is a safety requirement rather than a preference. Electrical equipment is listed for use with specific fuse classes, and the interrupting rating of the installed fuse must exceed the available fault current at that location. A fuse of inadequate interrupting rating can rupture rather than clear a fault safely, and a class substitution can void the equipment listing and expose downstream components to let-through energy above their withstand rating.

Confirm that the class, amperage, voltage rating, and dimensions match the original fuse and that the fuse holder accepts the class. De-energize and lock out the circuit and verify absence of voltage before servicing.
