General Electric | AC425NI | Fusible Bus Plug | 400A | 240V

Introducing the General Electric AC425NI Fusible Bus Plug, a purpose-built solution for safeguarding electric distribution systems. Designed for maintenance, retrofit, and replacement projects, this 400A, 240V fusible bus plug delivers reliable protection where exact specifications matter.

Key specifications

• Amperage: 400A
• Voltage: 240V
• Part number: AC425NI
• Manufacturer: General Electric

Important notes: Confirm fit and ratings before ordering. The part number AC425NI is the most reliable reference for compatibility, helping you avoid mismatches in panel assemblies and protection schemes.

Why this fusible bus plug is essential

Fusible bus plugs are a critical component in electrical protection, enabling quick, controlled interruption of fault currents to protect transformers, feeders, and downstream equipment. The AC425NI is engineered to align with GE’s enclosure geometries and protection interfaces, ensuring a clean integration path with existing gear and minimal downtime during replacement or retrofits.

Use cases and practical benefits

• Replace aging protection components to restore optimal fault protection without altering the surrounding panel setup.
• Retrofit: Update older systems to current protection standards while maintaining the same form factor and connection points.
• Replacement: Quick, reliable swap-in for GE-equipped panels requiring 400A at 240V, reducing project timelines.
• Compatibility certainty: Use the AC425NI part number as your primary reference to verify exact fit across GE-compatible equipment.

Practical tip: When planning installations or replacements, document the exact amperage, voltage, and part number (AC425NI) to streamline procurement and ensure you’re ordering the correct fusible bus plug for your GE distribution system.
