Bussmann DFJ-80 80A 600V AC line protection

SKU CH-GWDY-311P9

Fast-acting 80 A Class J fuse rated 600 V AC with 200 kA interrupt capacity

  • Fast-acting protection clears faults quickly
  • 80 A rating matches high-current circuits
  • 600 V AC rating suits industrial voltage levels
  • 200 kA interrupt rating handles severe short circuits
  • Bolt-on body fits standard J-class fuse blocks

Bussmann DFJ-80 Fast-Acting Fuse

The Bussmann DFJ-80 is a UL Class J fuse rated for 80 amps at 600 volts AC and 450 volts DC. It provides fast-acting overcurrent protection for electrical circuits in industrial and commercial installations. The bolt-on body style fits non-rejection fuse blocks such as the JM600 series.

Suited for standard Class J applications

This fuse suits engineers and maintenance teams specifying a non-indicating, fast-acting Class J device with a 200kA interrupt rating at 600 volts AC. Buyers who need visual indication of a blown element or a rejection-style body for code-mandated fuse-block keying should look at a different series.

80A 600V AC Class J rating

The decisive specification is the 80 amp, 600 volt AC Class J rating combined with a 200kA interrupt capacity at that voltage. Confirm the circuit requires exactly this amperage and voltage class before ordering.

Questions about this item

What current and voltage does the Class J 80A fuse interrupt at its 200kA rating?

The fuse is rated to interrupt 200kA at 600 V AC and 100kA at 450 V DC.

What fuse block series accepts the 4-5/8 in by 1-1/8 in bolt-on body?

Compatible blocks include the JM600 series designed for non-rejection Class J fuses.

Does the fuse have an indicator window, and which way do the bolt tabs face during install?

It is non-indicating; install with bolt tabs aligned to the block terminals and torque to the block manufacturer's specification.
