Bussmann RES-35 – Frequently Asked Questions

1) Will a Bussmann RES renewable fuse fit my existing Class H fuse holder?
Yes, as long as the holder is Class H and rated 600V. The RES is built to Class H dimensions, so it drops into standard Class H clips and blocks of the same voltage and amp rating. Note that a 600V Class H fuse body is physically longer than a 250V Class H fuse of the same amperage, so a 600V RES will not seat in a 250V holder.
2) Is a 10 kAIC interrupting rating enough for my panel?
The RES is rated 10 kAIC at 250 Vac. If the available fault current at your equipment exceeds that, or the equipment short-circuit current rating requires a higher AIC, this fuse is not the right choice. Many modern service and motor control applications call for 100 kAIC current-limiting protection, which means a Class RK5, RK1 or Class J fuse instead of Class H.
3) Class H versus Class RK5, which should I use for motor and HVAC circuits?
Class H like the RES is non current-limiting, so it clears a fault without cutting let-through energy the way a current-limiting fuse does. It is the code-familiar choice for older panels already built around Class H, and for general lighting and equipment branch circuits. If you need current limitation for equipment SCCR, or a time-delay characteristic that rides through motor inrush, go to an RK5 dual-element fuse, which fits the same Class H holder in a rejection-style or standard clip.
4) What does renewable mean on a Bussmann RES fuse, and can I really reuse the body?
Renewable means the fuse body takes a replaceable link. When the element opens, you replace the link rather than scrapping the whole fuse, which is why maintenance shops stocked them for legacy panels. The RES is non-indicating, so there is no window or pop-out pin telling you which one blew, you have to test it.
5) Can I use the 600V RES fuse on a 240V or 120V circuit?
Yes. A fuse may be applied at or below its voltage rating, so a 600V RES works on 480V, 240V and 120V systems. Be aware the interrupting capability published for the RES is 10 kAIC at 250 Vac, so verify available fault current against that figure before applying it on a higher-voltage system.
6) I'm standardizing fuse stock across a building. Is the RES a good fleet item?
It works where the panels are already Class H, 600V, and the fault current is within 10 kAIC. Because Class H dimensions are standardized, one amp rating covers every holder of that size across the site, and the RES ships in standard packaging rather than a special pack. Where you have newer gear with a stated short-circuit current rating, you will need a current-limiting class instead, so expect to carry two families rather than one.
7) How do I order the exact RES fuse I need?
The part number carries the amperage: RES-3 is the 3 amp, RES-5 the 5 amp, RES-35 the 35 amp. Amperage is the only option to specify, everything else on the RES is fixed at 600V, Class H, non-indicating, non current-limiting.
