Mersen u09617 End Barrier 600V 60A Class J Fuse Block

Product Description

The MERSEN u09617 is an end barrier designed to terminate and electrically isolate Class J fuse block assemblies in panelboards and distribution equipment. It mounts at the end of a fuse block run to prevent accidental contact with live terminals and to provide a clean, code-compliant finish to the assembly. Rated for 600 volts and 60 amps, this barrier is suited for industrial and commercial installations where Class J fusing is specified for branch-circuit or feeder protection. Licensed electricians and panel technicians are the primary installers of this component.

This end barrier is intended for use with Class J fuse blocks in commercial and industrial power distribution panels. It is commonly installed during new construction or retrofit projects where fuse block assemblies require proper terminal termination. The component fits into the fuse block assembly to cap the end position, maintaining phase spacing and providing a protective boundary between energized components and adjacent surfaces or enclosure walls.

Key Features

• Rated for 600 volts, suitable for standard commercial and industrial distribution voltages
• 60-amp rating consistent with Class J fuse block ampacity
• Designed specifically for Class J fuse block assemblies
• Provides electrical isolation and physical protection at the terminal end of the fuse block run
• Supports code-compliant panel assembly and finger-safe installation practices

Compatibility

Designed for use with Class J fuse blocks rated up to 600 volts and 60 amps.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the panel or distribution equipment completely before handling any fuse block components. Confirm the end barrier is fully seated and secured on the fuse block before restoring power. Do not modify or trim the barrier to fit non-compatible block configurations.
