General Electric | FVK445JK6 | Fusible Bus Plug | 450A | 600V

The General Electric Fusible Bus Plug FVK445JK6 is a purpose-built, 450A, 600V device designed to protect and power high-demand electrical feeders. Specifically engineered to integrate with GE bus assemblies, it supports essential maintenance, retrofit, and replacement projects where exact specifications matter.

What it does

In an electrical distribution path, this fusible bus plug provides a controlled fuse-link that quickly interrupts fault current to prevent damage downstream. When a fault occurs, the fusible element opens, isolating the affected circuit while keeping the rest of the system energized. Built for robustness, it helps minimize downtime and maintain system reliability in industrial panels and switchgear.
