Bussmann DFJ-70 J Class Fuse 70A 600V AC

SKU CH-WA0V-VSY18

A 70 A fast-acting Class J fuse rated for 600 V AC and 450 V DC with 200 kA and 100 kA interrupt ratings

  • Fast-acting protection clears faults quickly
  • 70 A rating suits medium-load circuits
  • 600 V AC rating covers industrial supplies
  • 200 kA interrupt capacity handles severe shorts
  • Bolt-on body fits JM600 fuse blocks directly

J Class Fast-Acting Fuse

This J Class fuse provides fast-acting overcurrent protection rated at 70 amps and 600 volts AC. It is designed for industrial and commercial power circuits that require a high interrupting capacity in a bolt-on form factor.

Bolt-On Installation and Fit

The fuse body measures four and five-eighths inches long with a one and one-eighth inch diameter and uses a bolt-on mounting style. It fits non-rejection fuse blocks such as the JM600 series, so installers must verify block compatibility before wiring.

Suited for High-Fault Current Panels

This fuse suits panels needing 200kA AC or 100kA DC interrupt ratings with a melamine body and single-element construction. Buyers who need indication features, rejection-style mounting, or a different ampere rating should look at other options.

Highlights

  • Fast-acting protection clears faults quickly
  • 70 A rating suits medium-load circuits
  • 600 V AC rating covers industrial supplies
  • 200 kA interrupt capacity handles severe shorts
  • Bolt-on body fits JM600 fuse blocks directly

Questions about this item

How can I verify the fuse is functioning correctly after installation?

With power off, use a multimeter on the continuity setting across the fuse terminals; a reading near zero ohms confirms the element is intact and the DFJ-70 is ready for service.

What comes in the package and what additional hardware is required?

The box contains the DFJ-70 fuse only; you must separately supply a compatible JM600 series fuse block or equivalent bolt-on holder rated for Class J fuses.

Which rating should I select for a 600 V AC circuit needing 70 A protection?

Choose the DFJ-70 rated 70 A at 600 V AC with a 200 kA interrupt rating; it matches the voltage, current and Class J requirements for that application.
