60 A Class J Fast-Acting Fuse
The Bussmann DFJ-60 is a 60 A, 600 V AC Class J fuse designed for fast-acting overcurrent protection in electrical distribution systems. Its cylindrical melamine body measures 2-3/8 in length by 1-1/16 in diameter and fits non-rejection fuse blocks. The single-element construction provides a 200 kA interrupt rating at 600 V AC and 100 kA at 450 V DC.
Suits 60 A Class J circuits needing fast response
This fuse suits panels and equipment requiring a 60 A Class J fast-acting link with high interrupt capacity. It is not for circuits needing time-delay characteristics to ride through motor inrush or transformer magnetising current. Buyers who need visual indication of a blown element should select an indicating model instead.
Simple cylindrical insertion into compatible blocks
Installation consists of inserting the cylindrical body into a matching Class J non-rejection block such as the CH60J, JM600, JT600 or JTN600 series. Ensure the block is rated for the available fault current and that the fuse orientation matches the holder. The most common error is fitting the fuse into a rejection-style block that physically rejects the non-rejection blade design.

Questions about this item
What fuse block series will accept the 2-3/8 in by 1-1/16 in cylindrical body of this DFJ-60 fuse?
Compatible fuse block series include CH60J, JM600, JT600 and JTN600, which are designed for the non-rejection style body of this Class J fuse.
Can this 60 A Class J fuse protect circuits that also use older 600 V AC equipment rated for lower interrupting capacity?
Yes, the 200 kA interrupt rating at 600 V AC provides ample margin for legacy gear with lower withstand ratings, while the 100 kA rating at 450 V DC covers older DC systems.
How can I verify the fuse is intact after installation without an indicating feature?
Use a multimeter to measure continuity across the fuse terminals; a low resistance reading confirms the single element is intact and the fuse is ready to protect the circuit.
