The Battery Mount Grounding bar and ZCASE® Fuse Holder with Busbar (BMZB) series allows you to mount additional ground wires or fusing directly to a post-style battery terminal. It also offers the option of adding fused outputs to a pair of type 31 batteries. This series offers a compact solution with an integrated busbar, which consolidates complex wiring around a battery system, eliminating or reducing the need for additional wiring.

By creating additional grounding and fusing locations outside of the main fuse box, these products help reduce cabling and assembly time and provide localized circuit protection without modifying the existing battery harness.

The fuse holder products are designed to mate with M8 ZCASE® fuses, and are rated to operate up to 400A continuously. This series mounts directly to the battery post with all necessary hardware coming pre-assembled. Available in 2-position grounding bar, 3-position fuse holder for SAE/DIN post style batteries, or 4-position configuration for type 31 style batteries, this series serves as a scalable circuit protection solution.
