Bussmann REN-5 – Frequently Asked Questions
1) What does it mean that the Bussmann REN fuse is renewable?
The REN series is a renewable Class H fuse, meaning the fuse body opens and the blown link is replaced rather than the whole fuse being discarded. It is a non current-limiting design, so it will not reduce available fault current the way a current-limiting Class J or RK fuse does. Interrupting rating is 10 kAIC at 250V.
2) Can I use a Bussmann REN 250V fuse in a 480V circuit?
No. The REN series is rated 250V only and must not be applied on a 480V system. For a higher voltage circuit you need a fuse rated at or above the system voltage, such as a 600V Class H or Class RK unit.
3) Will the REN-50 fit ferrule style fuse clips?
Yes. The REN-50 is a ferrule end by ferrule end fuse, so it drops into standard Class H ferrule clips. Its body measures 0.82 x 0.82 x 2.98 inches. Class H ferrule fuses at 50A and below share common dimensions with Class K and RK ferrule fuses of the same rating, so the clip spacing in an existing 250V/60A disconnect will accept it.
4) Is the REN a time delay fuse for motor loads?
The REN is a Super Lag, time lag fuse, so it tolerates motor inrush rather than opening on starting current. That makes it suited to motor and transformer circuits on 250V systems, within its 10 kAIC interrupting limit.
5) Can a renewable REN fuse replace a one time Class H fuse in the same disconnect?
Yes, within the same class, voltage and amp rating. Both are Class H, 250V, 10 kAIC ferrule fuses, so a REN-50 goes into the same clips as a one time 50A Class H fuse. The difference is maintenance practice: the renewable body accepts replacement links instead of being thrown away, which some jurisdictions and facility standards no longer permit for new work.
6) Does the Bussmann REN fuse have a blown fuse indicator?
No, the REN series is non indicating. There is no window or pop-up pin, so a blown unit has to be confirmed with a meter or by pulling the fuse. If a maintenance crew needs visual identification, specify an indicating fuse instead.
7) How many Bussmann REN fuses come in a carton?
REN fuses are packed 10 to a carton in standard packaging. Useful to know if you are stocking a spares crib and want full cartons per amp rating rather than loose pieces.
