Bussmann HRK-R – Frequently Asked Questions
1) Can the Bussmann HRK-R fuseholder be used on a 120V branch circuit?
No. The HRK-R is rated 32 volts, so it belongs in low-voltage work: automotive, marine, and low-voltage control wiring. For line-voltage branch circuits you need a fuseholder rated for that system voltage, not this one.
2) What is the maximum amperage the Bussmann HRK-R fuseholder will carry?
15 amps. That is the holder's ceiling, so the fuse you drop into it must be 15A or less, sized to the conductor and load you are protecting. Running a higher-rated fuse in it overloads the holder itself.
3) Will a Bussmann HRK-R work for a 12-volt DC marine or automotive circuit?
Yes. A 32V-rated holder covers 12V and 24V DC systems, and marine and automotive wiring is exactly what this one is built for. Keep the fuse at or below 15A.
4) What is the difference between the Bussmann HRK-R fuseholder and the Littelfuse 155400 in-line fuseholder?
The Bussmann HRK-R is a 1-pole universal fuseholder rated 32 volts and 15 amps, designed to be mounted in a panel, harness, or piece of equipment where the holder is fixed in place. The Littelfuse 155400 is an in-line ATO fuseholder from the 155 series rated 20 amps, which splices into the run of a wire rather than mounting to a surface. Choose the HRK-R where you want a retained fuse at a fixed point in the assembly, and the in-line style where the holder hangs in the harness itself.
5) I need a fuseholder for a circuit drawing more than 15 amps. What should I use instead of the Bussmann HRK-R?
The Bussmann HRK-R is rated 15 amps, so for a circuit above that rating step to a higher-rated holder such as the Littelfuse 155400 in-line fuseholder, which is rated 20 amps and takes ATO blade fuses. Size the holder to the circuit rather than relying on the fuse alone, since the holder rating is the ceiling for continuous current through the assembly.
6) How many circuits does the HRK-R fuseholder protect?
One. It is a single-pole holder, so each HRK-R carries one fuse protecting one circuit. If you are fusing several legs in a panel or harness, you either use one holder per leg or step up to a multi-pole block.
7) Is the fuse included with the Bussmann HRK-R?
The HRK-R is the fuseholder only. It houses and retains a standard fuse, which is ordered separately in the amperage your circuit calls for, up to the holder's 15A rating.
8) Will the Littelfuse 155400 drop into the same spot as a Bussmann HRK-R?
No, they are not interchangeable mounting-wise. The Bussmann HRK-R is a 1-pole universal fuseholder with a compact housing meant to be installed in panels, harnesses, and equipment wiring at a fixed location, while the Littelfuse 155400 is an in-line ATO holder that is spliced into the conductor and supported by the wire. Swapping one for the other changes how the holder is secured and which fuse body it accepts, so plan the harness accordingly.
9) What part number do I give my supplier for the Bussmann universal fuseholder?
Bussmann HRK-R. It is a single model, no finish or size options to specify, and that same designation is what OEM and replacement sourcing lists it under.
