SAMI Fuse Covers, Indicating and Non-Indicating

SAMI fuse covers

Bussmann™ series Safety and Maintenance Improvement (SAMI™) fuse covers for UL® Class CC, G, H(K), J and UL supplemental (midget) fuses. Available in open fuse indicting and non-indicating versions, SAMI fuse covers provide a convenient means to help improve safety by providing a cover that snaps on fuses that are mounted in open-style fuse blocks from various manufacturers.

Order one cover per block pole.

For new installations, we recommend using Bussmann series modular fuse blocks that have optional IP20 finger-safe covers in indicating and non-indicating versions. See related products below.
