General Electric | AC421WG | Fusible Bus Plug | 4-Pole

General Electric AC421WG Fusible Bus Plug — a precisely engineered OEM component designed for dependable protection and straightforward maintenance within electrical distribution systems. This 4-Pole plug delivers a compact, multi-circuit solution for GE-compatible gear, enabling safe isolation and controlled fault paths during servicing or retrofits.

Key benefits that set this part apart:

• 4-Pole configuration provides multiple independent paths in a single plug, simplifying wiring and reducing the need for extra components in multi-circuit panels.
• Authentic GE part AC421WG guarantees compatibility with General Electric equipment and replacement assemblies, minimizing guesswork during repairs or upgrades.
• Fusible protection built into the plug offers an integrated safety path, supporting safer maintenance workflows and faster return-to-service for protected circuits.
• Maintenance, retrofit, and replacement ready — specifically suited for projects where exact specifications matter and precise part matching is essential.
• Clear compatibility reference — the part number AC421WG is the best reference for ensuring a correct fit; always confirm ratings and mechanical fit before ordering.

Practical use cases you can rely on:

• Maintenance: swap in the fusible bus plug to isolate and protect circuits during panel work, then reseat to resume normal operation.
• Retrofit: upgrade legacy panels to a 4-pole fusible path to support expanded circuits or updated protection schemes.
• Replacement: quickly replace a worn or failed bus plug with an authentic GE component that matches OEM specifications and mounting interfaces.

Buying with confidence: before you order, verify that the AC421WG matches your equipment’s ratings and mechanical footprint. Use the part number as your primary compatibility reference, and consult your equipment’s BOM or service manual to confirm fitment.
