General Electric | SB323I | Fusible Bus Plug | 100A | 3-Pole | 240V

General Electric SB323I Fusible Bus Plug is a genuine GE component designed for panels that require a 100A, 3-pole, 240V fusible bus plug. Built for reliability in maintenance, retrofit, and replacement projects, this part aligns with exact specifications to keep your electrical system operating safely and efficiently.

• Amperage: 100A
• Poles: 3-Pole
• Voltage: 240V
• Type: Fusible Bus Plug
• Manufacturer: General Electric
• Part Reference: SB323I (best reference for compatibility)

What sets the SB323I apart is its purpose-built design for three-phase electrical systems within GE panels. The fusible bus plug format provides a predictable, contained means of interrupting current when protection is needed, while preserving mounting geometry and panel layout. This isn't a generic retrofit part—it’s a stock-ready GE component that partners with the panel architecture you already rely on, helping minimize downtime and ensure consistent protection performance.

Ideal use cases include:

• Routine maintenance where a like-for-like replacement is required to restore original protection characteristics
• Retrofits to upgrade or adapt a GE panel to a 100A, 3-pole, 240V configuration
• Replacement of a worn or failed fusible bus plug to maintain system reliability
• Emergency part replacement to shorten outage windows and keep projects on schedule

Important compatibility and installation notes: always confirm fit and ratings before ordering. The part number SB323I is the most reliable reference for ensuring compatibility with your GE equipment. When installing, ensure power is fully de-energized, verify that the panel is rated for 240V and 3-pole operation, and replace the bus plug with an identical configuration to maintain protective coordination. If in doubt, reference your panel’s service documentation and match the amperage, pole count, and voltage exactly to avoid mismatches.
