DiversiTech Fuse 70A 250V Class K5 1 NLN070

The DiversiTech NLN070 is a 70 amp, 250 volt Class K5 fuse used for branch circuit and feeder protection in commercial and industrial distribution equipment.

Class K5 fuses provide moderate current limitation with a defined interrupting rating, positioning them between basic renewable fuses and the higher performance current-limiting classes. They are specified where the available fault current at the point of installation is within the fuse interrupting rating and where the equipment does not require the tighter let-through characteristics of Class RK1 or Class J devices.

The 250 volt rating suits single phase 120/240 volt systems and three phase 240 volt systems, covering a substantial portion of light commercial and industrial distribution. The 70 amp rating serves feeders and larger branch circuits including motor loads, HVAC equipment, and distribution subpanels.

Applications include fused safety switches and disconnects, panelboard and switchboard protection, motor branch circuits, air conditioning and refrigeration equipment feeders, and general distribution in commercial buildings.

Fuse class selection is not a matter of preference. The equipment in which the fuse is installed carries a listing based on specific fuse classes, and the available fault current at the installation point must not exceed the fuse interrupting rating. Substituting a different class can invalidate the equipment listing and, more seriously, may leave downstream components exposed to fault energy beyond their withstand rating.

Before replacement, verify the class designation, amperage, voltage rating, and physical dimensions match the original, and confirm the holder or switch accepts that class. De-energize and lock out the circuit, verify absence of voltage, and follow applicable electrical code and equipment instructions.
