Key specs

• Amperage: 400 A
• Poles: 4-Pole
• Voltage: 600 V
• Type: Fusible bus plug

Compatibility and reference: The part number FVK49EB is the best reference for compatibility. Before ordering, confirm fit and ratings with your gear’s documentation or OEM catalogs to ensure seamless interchange with GE bus work.

Why this fusible bus plug stands out

Unlike generic replacements, this plug is purpose-built for GE equipment, matching the electrical interface, mounting geometry, and protective characteristics required by 400 A, 600 V distribution paths. The fusible design delivers built-in overcurrent protection, enabling controlled disconnection to protect downstream equipment during faults or maintenance.

Ideal use cases

• Maintenance outages on GE switchgear or distribution panels needing a precise, compatible fusible plug.
• Retrofits to upgrade or restore 400 A, 4-pole, 600 V bus paths without reconfiguring the entire assembly.
• Replacement parts during scheduled replacement cycles to minimize downtime and keep systems aligned with OEM specs.

Practical tips for installation and maintenance

• Verify the bus plug interface, current rating, and voltage rating against your equipment’s nameplate and GE manuals before installing.
• Handle with standard electrical safety procedures; ensure the power is isolated and the correct test procedures are followed.
• Keep a spare FVK49EB on hand as part of a maintenance inventory to reduce downtime during service windows.
