General Electric | AC426N | Fusible Bus Plug | 600A | 240V

General Electric AC426N Fusible Bus Plug is a purpose-built protection component designed to deliver reliable, ready-to-install overcurrent protection in your electrical distribution system. Engineered to GE’s exacting standards, this 600A, 240V fusible bus plug is ideal for maintenance, retrofit, and replacement projects where precise ratings and a perfect fit matter.

Key specs and compatibility

• Amperage: 600A
• Voltage: 240V
• Part number: AC426N (the best reference for compatibility)

Note: Confirm fit and ratings before ordering. The exact part number is the most reliable reference when matching to your gear.

Why this fusible bus plug stands out

Unlike generic substitutes, the AC426N is built to integrate with GE switchgear and bus systems, ensuring dependable protection without needing custom adaptations. Its fusible design provides fast-acting interruption to prevent damage from overloads or faults, while the 240V rating matches common distribution panels and equipment in commercial and industrial settings.

• Fit-forward design: specifically aligned with applications that specify the AC426N, reducing installation guesswork.
• Precise protection: 600A rating to match upstream feeders and circuit features in mid-to-large distribution networks.
• Retrofit-friendly: a practical option for updating protection on aging gear or expanding capacity without replacing entire assemblies.

Ideal use cases

This fusible bus plug excels in:

• Maintenance on GE-based switchgear where fusible bus plugs are part of the protection scheme.
• Retrofits that upgrade protection to 600A for 240V circuits within existing systems.
• Replacement of damaged or degraded bus plug components to restore safe, reliable operation.
• Facilities upgrading grids or reorganizing feeders, where matching spec components streamline compatibility.

Practical tips for buyers

• Keep the part number visible during ordering—AC426N is the best compatibility reference.
• Verify system voltage (240V) and current ratings (600A) before purchasing.
• Plan installation during planned maintenance windows to minimize downtime.
• Inspect surrounding bus connections for wear or corrosion and address prior to integrating a new fusible plug.

Why choose GE for fusible bus protection

General Electric brings decades of reliability to power distribution components. The AC426N offers a part that is designed to align with established GE equipment and protection schemes, supporting safer operation and easier service planning.
