Bussmann Eaton DFJ Series Class J High-Speed Fuse, Non-Indicating

The Bussmann Eaton series DFJ Class J high-speed fuse delivers dependable overcurrent protection for demanding industrial, commercial, and solid-state electrical systems. Rated 600 Vac or less and 450 Vdc or less, this Non-Indicating, ferrule end X ferrule end fuse is housed in a durable Melamine tube built to Class J dimensional standards. The DFJ series is available in 24 amp ratings, from 1A through 600A, so specifiers and electricians can match the exact protection level required for a given circuit, and the line is CE Marked for use in professional power distribution and motor branch-circuit applications.

Key Features

  • Amp Rating Range: Offered in 24 ratings from 1A to 600A, allowing precise selection for motor, feeder, and branch-circuit protection needs.
  • Voltage Rating: Rated 600 Vac or less and 450 Vdc or less, suitable for both AC and DC circuit protection.
  • High Interrupting Capacity: Engineered for high interrupting performance, with ratings up to 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc depending on the amp rating selected.
  • Class J Design: Manufactured to Class J dimensional and mounting standards for compatibility with standard Class J fuse blocks, holders, and disconnects.
  • Ferrule End Connection: Ferrule end X ferrule end configuration for secure, low-resistance termination in compatible fuse holders.
  • Durable Melamine Tube: Melamine tube body construction provides mechanical strength and reliable insulation under fault conditions.

Bussmann DFJ-35 – Frequently Asked Questions

1) Will a Bussmann DFJ fuse fit my existing Class J fuse block?
Yes. The DFJ series is built to Class J dimensional and mounting standards, so it drops into standard Class J blocks, holders, and fused disconnects. Terminations are ferrule end by ferrule end, which is the Class J norm across the 1A to 600A span, so there are no bolt-on lugs to account for.
2) Can I use a DFJ Class J fuse on a DC circuit, like a drive bus or battery system?
Yes, within limits. The DFJ is rated 600Vac or less and 450Vdc or less, so it is usable on DC buses up to 450V. Interrupting rating runs up to 200 kAIC at 600Vac and 100 kAIC at 450Vdc depending on the amp rating you pick.
3) Is the DFJ a high-speed semiconductor fuse or a normal time-delay Class J?
High speed, not time delay. The DFJ uses a fast-acting element intended to protect semiconductors and solid-state devices, which is why it turns up on VFD and rectifier circuits. If you are sizing for motor inrush and want the fuse to ride through starting current, a time-delay Class J is the better choice; the DFJ is for when the silicon needs to survive the fault.
4) Can I swap a DFJ into a Class J holder that currently has a regular Class J fuse in it?
Physically yes, since both are built to the same Class J dimensions and use ferrule ends. Electrically it is a different fuse: the DFJ is high speed rather than time delay, so it will open faster on overload and inrush. Re-check your motor starting current and any selective coordination before you make the substitution, and confirm the amp rating you need is one of the 24 offered.
5) Does the Bussmann DFJ have a blown-fuse indicator?
No. The DFJ is a non-indicating fuse, so there is no visual pop-up or pin to show it has opened, and nothing to drive a microswitch off. If your panel design relies on indication or remote blown-fuse signaling, you need an indicating Class J or a separate blown-fuse detection scheme.
6) What amp ratings does the Bussmann DFJ series come in?
24 ratings across the line: 1, 2, 3, 4, 8, 10, 12, 35, 45, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 300, 400, 450, 500 and 600A. Note the gaps, there is nothing between 12A and 35A, or between 225A and 300A, so if your coordination study calls for 20A or 250A you will need to move to the next available step or a different series.
7) How do I order the right DFJ, and what is the part number format?
Part numbers follow the amp rating directly: DFJ-1 for 1A, DFJ-125 for 125A, DFJ-600 for 600A. A few ratings carry a W suffix, including DFJ-70-W, DFJ-80-W, DFJ-90-W and DFJ-100-W, so quote the exact number rather than assuming a plain DFJ-100 exists. Packaging is standard.
8) What is the DFJ fuse body made of, and does it hold up in a hot industrial panel?
The body is a melamine tube. Melamine is used here for mechanical strength and for insulation integrity when the fuse clears a fault, which is what you want in a densely packed industrial distribution or drive panel.
9) Is the Bussmann DFJ fuse CE marked for an export machine build?
Yes, the DFJ series is CE Marked, which covers it for machine panels destined for European markets.
