The Littelfuse ZCASE® BMZF Series 32V Bolt-Down Forged Battery-Mounted Fuse Holder features a built-in battery clamp, which allows the installation of ZCASE® M10 fuses (sold separately) directly on a post-style battery terminal. Made with forged brass, the compact battery post fuse holder is designed for heavy-duty, high-current applications in crowded spaces.

Utilizing a special insulated bolt, the ZCASE® BMZF Series fuse holder ensures reliable high-current connections. The metal bolt head and mineral isolating washer enable the proper torque application and help prevent torque reduction over time. The bolt assembly also features an integrated isolation shell to prevents current from bypassing the fuse element.

The ZCASE® BMZF Series is available as a single-fuse holder as well as a multi-fuse holder (2- or 3- position). Kits come with a red UL 94 rated cover to help prevent accidental contact with the fusing.
