The Innovative, Snap-Together Solution: Eaton's Bussmann Series Modular Ferrule Fuse Blocks

Bussmann Modular Ferrule Fuse Blocks

Overcurrent Protection In A Snap

The modular ferrule fuse blocks make it easier to apply fusible overcurrent protection from control and lighting circuits to HVAC/R equipment and industrial machinery. With a clever, snap-together design and optional covers, these handy fuse blocks speed installation, increase flexibility, and enhance safety for the installer, customer, and end user.

With tool-less assembly of multiple pole blocks at point-of-use, you save on inventory and assembly time. Featuring a compact design with a minimal footprint, modular ferrule fuse blocks deliver the most efficient use of panel space within alternative energy, commercial construction, and electrical panel OEM applications.

Lockout/Tagout Safe

For added safety, the IP20 finger-safe covers protect maintenance personnel from contacting energized terminals, and provide a lockout/tagout provision for downstream maintenance. The IP20 optional cover, lockout/tagout feature, and optional open fuse indication help to enhance overall maintenance safety while reducing troubleshooting time.
