Bussmann Eaton Series REN Renewable Fuse, Class H 250V
The Bussmann Eaton Series REN Renewable Fuse is a non-current-limiting, renewable Class H fuse designed for general-purpose branch-circuit protection. This Series REN family is available in 7A, 25A, and 45A ratings, each rated 250 Vac with a 10 kAIC interrupt rating for dependable overcurrent protection. The renewable design lets the internal fusible element be replaced in the field rather than discarding the entire fuse body, making Series REN a cost-effective choice for facilities that maintain renewable fuse holders.

Bussmann REN-25 – Frequently Asked Questions
1) What does it mean that the Bussmann REN fuse is renewable, and do I have to throw it away after it blows?
Renewable means the fusible link inside the REN body can be replaced in the field instead of scrapping the whole fuse. That is the reason facilities with existing renewable fuse holders keep stocking Class H renewable fuses. Note the body is non-indicating, so there is no visual blown indicator - you test the circuit or the fuse to confirm it opened.
2) Can I use a Bussmann REN Class H fuse on a 480V circuit?
No. The REN renewable fuse is rated 250 Vac only, so it must not be applied above that. A 480V circuit needs a fuse rated 600V for that voltage class. Applying a 250V fuse on a higher-voltage system risks failure to interrupt.
3) Will a REN renewable fuse protect equipment that requires current-limiting protection?
No. REN is non-current-limiting construction. If a piece of gear is marked for use with current-limiting fuses, or a series-rating or component protection scheme depends on current limitation, a Class H renewable fuse will not satisfy it. Use a Class RK, J, or T current-limiting fuse in that case. REN suits general-purpose branch and feeder overcurrent protection where current limitation is not required.
4) Will a Class H REN fuse fit my existing fuse block, or do I need a different holder?
Class H fuses use the standard NEC dimensions for their amp range, so a 250V Class H fuse drops into the same clips as the Class H fuse it replaces. Below 60 amps, a Class H and a Class R fuse share the same overall length, but a Class R rejection clip will not accept a Class H fuse - rejection features are one-way. So REN goes into a plain Class H block, not into a rejection-type block.
5) What amp ratings does the Bussmann REN renewable fuse come in?
Three ratings are offered across the 7A to 45A range: REN-7 at 7 amps, REN-25 at 25 amps, and REN-45 at 45 amps. All three share the same 250 Vac, 10 kAIC Class H rating, so the only selection decision is the amperage your circuit and conductor require.
6) Do REN fuses ship individually or in a box?
Standard packaging is a carton of 10 fuses. That is how they are stocked, which works out well for MRO crews keeping spares of a single amp rating on the shelf for a fuse-panel building.
7) Where are Bussmann REN renewable fuses typically used?
Branch-circuit and feeder protection in older commercial and industrial fused distribution - panelboards, load centers, and disconnects built around renewable fuse holders. They are a maintenance item for buildings that still run Class H renewable equipment rather than a first choice for new gear, where current-limiting classes are the norm.
