Bussmann FLJ Maxi Fuse, Time-Delay, Non-Indicating, 32VDC

The Bussmann FLJ Maxi Fuse is an EATON Bussmann Series time-delay fuse rated 32 Vdc with a 1 KAIC interrupt rating, built in a non-indicating, non-illuminating design for straightforward overcurrent protection. This family is available in 45A, 65A, and 75A amp ratings, giving installers a consistent Maxi Fuse platform across a 45A-75A range for DC power distribution and equipment protection circuits. The time-delay characteristic allows the fuse to ride through momentary inrush and transient current spikes without nuisance opening, while still clearing sustained overloads reliably. Whether protecting a single 45A branch circuit or a larger 75A load, the Maxi Fuse form factor keeps replacement and stocking simple across the range.

Key Features

  • Amp Rating Range: Available in 45A, 65A, and 75A ratings to match the current demands of the circuit being protected.
  • Voltage Rating: Rated 32 Vdc for DC power distribution and low-voltage circuit protection.
  • Interrupt Rating: 1 KAIC interrupt capacity for dependable fault clearing under overcurrent conditions.
  • Time-Delay Operation: Time-delay design tolerates brief current surges and inrush without opening prematurely.
  • Non-Indicating Design: Non-indicating construction keeps the fuse body simple, with no blown-fuse indicator window.
  • Non-Illuminating: Non-illuminating housing, with no built-in illumination feature.
  • Maxi Fuse Form Factor: Standard Maxi Fuse footprint compatible with common Maxi Fuse holders and blocks.

Technical Specifications

  • Packaging Type: Standard
  • Fuse Indicator: Non-indicating

Typical Applications

  • DC Power Distribution Circuits
  • Overcurrent Protection for Electrical Systems
  • Industrial and Commercial Equipment Wiring
  • Replacement Fuse for Time-Delay Circuit Protection
  • Maxi Fuse Holder and Fuse Block Assemblies

Why Bussmann?

Bussmann, part of the EATON Bussmann Series lineup, builds this Maxi Fuse with a clear 32 Vdc, 1 KAIC rating and a time-delay response so electricians and technicians can size protection with confidence. The non-indicating, non-illuminating construction keeps the design straightforward, and the 45A-75A range means the same trusted Maxi Fuse platform scales to fit the circuit at hand. Choose Bussmann for consistent, code-aware overcurrent protection on DC electrical systems and equipment.

Bussmann FLJ-45 – Frequently Asked Questions

1) Will a Bussmann FLJ Maxi fuse fit a standard Maxi fuse holder or block?
Yes. The FLJ is built on the standard Maxi (APX) blade footprint, measuring 1.25 in by 1.5625 in by .625 in, so it drops into common Maxi fuse holders, blocks and panel cavities that already take that body. If the holder in front of you takes an ATC/ATO blade fuse instead, the Maxi will not seat in it, those are a smaller body entirely.
2) Can I use a 32VDC Maxi fuse on a 120V AC circuit?
No. The Bussmann FLJ Maxi fuse is rated 32Vdc only, which covers 12V and 24V DC systems, vehicle and equipment power distribution, and low voltage DC panels. It is not an AC branch circuit fuse and must not be used on 120V or 277V line voltage. For AC service and feeder protection you want a cartridge fuse rated for that voltage class, not a blade fuse.
3) Will a time-delay Maxi fuse stop nuisance blowing on a motor or inverter circuit?
That is what the time delay characteristic is for. The FLJ rides through the brief inrush a motor, compressor, winch or inverter draws at startup instead of opening on it, while still clearing a sustained overload. A fast-acting fuse of the same amp rating on that same circuit is the one that keeps popping on startup. Time delay does not let you undersize the fuse, though, it only tolerates the surge.
4) What amp ratings does the Bussmann FLJ Maxi fuse come in?
Three: 45A (FLJ-45), 65A (FLJ-65) and 75A (FLJ-75). That is the whole range, so if your circuit calls for 30A or 100A the FLJ family will not cover it. Order by the amp rating stamped on the fuse you are replacing, not by the load you measured, unless you are sizing the circuit from scratch.
5) Is there a way to see at a glance whether a Bussmann FLJ fuse is blown?
No, the FLJ is a non-indicating, non-illuminating fuse. There is no LED or pop-up window that lights when the element opens, so you check it by eye through the body or with a meter across the blades. If your maintenance crew needs a visual blown-fuse signal on the panel, specify an indicating Maxi fuse instead, this one will not give you that.
6) Can I replace a blown Maxi fuse with the next size up if I do not have the right amp rating on the truck?
No. Going up in amperage on a Bussmann FLJ, say putting a 75A in place of a 45A, means the wiring and the device downstream are no longer protected at the level they were sized for. The three ratings are 45A, 65A and 75A and they are not interchangeable. Match the rating that was in the holder, and if the same rating keeps opening, the fault is in the circuit, not the fuse.
7) How do I order Bussmann FLJ Maxi fuses for MRO stock across several amp ratings?
The part number is the family plus the amperage: FLJ-45, FLJ-65, FLJ-75. All three share the same Maxi body at 1.25 x 1.5625 x .625 inches and the same 32Vdc, 1 kAIC rating, so one holder type and one shelf bin size covers all three and a tech can swap ratings without changing hardware. They ship in standard packaging, weighing .023 lb apiece, which makes them easy to carry on a service truck in quantity.
