Bussmann SAMI-3N – Frequently Asked Questions

1) Will the Bussmann SAMI cover fit Class R or Class T fuses, or only Class J?
Class J only. The SAMI dead-front cover is built to the Class J fuse envelope and is specified for use with Class J type fuses. Class R, Class T, and midget fuses have different body dimensions and mounting centers, so this cover will not seat on them. Match the cover to the fuse class stamped on the fuse you are covering.
2) What is the difference between the SAMI-3N and SAMI-6N fuse covers?
Amp range is the only difference between them. SAMI-3N is the 3A version and SAMI-6N is the 6A version, covering a 3A to 6A span. Both are non-indicating dead-front covers for Class J fuses rated 600 Vac / 600 Vdc. Pick the one that matches the amperage of the Class J fuse you have installed.
3) Will the SAMI fuse cover clear the door of my panelboard or fuse enclosure?
The SAMI cover measures 4.88 in long, 1.58 in high, and 1.15 in wide, and weighs .5 lb. That 1.58 in height is the figure to check against the space between your fuse block and the enclosure door or barrier, since a dead-front cover adds height above the fuse clips.
4) Can I use this Bussmann SAMI cover on a 600 Vdc circuit?
Yes. The SAMI Class J dead-front cover is rated 600 Vac and 600 Vdc, so it can be used on DC fuse circuits such as drive, battery, and solar disconnect sections as well as standard AC panelboard work.
5) Does this SAMI cover have a blown fuse indicator window?
No. This is the non-indicating version, a solid cover with no indicator window. You cannot tell a blown fuse by looking at it, so on circuits where you want visual fault indication you need an indicating SAMI cover paired with an indicating fuse instead.
6) Why would a facility electrician add a dead-front cover over an existing Class J fuse block?
It shields the live fuse terminals so someone opening the panel for routine work is not exposed to bare energized parts. Typical use is on panelboard and switchboard fuse assemblies, OEM fuse blocks, and retrofit work on older open fuse panels where finger-safe coverage was never provided.
7) Does the Bussmann SAMI cover come with the fuse, or do I order that separately?
The cover is a standalone accessory. It is a dead-front fuse cover only, so the Class J fuse and the fuse block or holder are separate line items. Order the fuse first, then match the SAMI cover to its class and amp rating.
