AC463RG 100A, 480/600V, 3-Phase, 4-Wire Fusible Bus Plug

The GE Armor-Clad 100A Fusible Bus Plug is purpose-built for robust, reliable protection in demanding 3‑phase, 4‑wire power systems operating at 480/600V. This fusible bus plug combines GE’s trusted Armor-Clad durability with precise overcurrent protection, helping you quickly isolate a fault and keep your critical equipment protected without sacrificing efficiency or space in your distribution scheme.

Why this fusible bus plug stands out

• 100A rating provides solid feeder protection for substantial loads without unnecessary nuisance openings.
• 480/600V compatibility aligns with common industrial distribution environments, reducing the need for adapters or voltage conversions.
• 3‑phase, 4‑wire configuration supports modern power systems with a dedicated neutral for balanced loads and safer fault handling.
• Fusible protection delivers fast electrical isolation during faults, helping prevent damage to downstream equipment and reducing downtime.
• Armor-Clad construction from GE delivers rugged reliability in harsh industrial settings, where vibration, dust, and temperature swings are routine.
• Easy integration into existing bus assemblies, enabling a streamlined upgrade path for aging infrastructures or new installations alike.

Ideal applications

• Industrial facilities and manufacturing lines that run high-load feeders on 480/600V systems
• Motor control centers and distribution panels needing dependable, plug-in protection for each feeder
• Make-ready or retrofit projects where space optimization and quick fault isolation are priorities
• Facilities aiming to improve uptime by reducing fault propagation and easing maintenance routines

How it works

In operation, the fusible bus plug sits in the appropriate 3‑phase, 4‑wire bus arrangement. When an overcurrent occurs, the fusible element interrupts the circuit, isolating the affected feeder and protecting downstream equipment. The result is faster fault response, clearer protection boundaries, and a safer, more maintainable power distribution system.

Practical guidance and tips

For dependable performance, pair this bus plug with compatible protective fuses and ensure the system voltage remains within the 480/600V range. Regularly inspect for signs of wear or corrosion on the enclosure, and replace any damaged components promptly to maintain protection integrity. This unit is ideal for crews seeking a durable, plug-in protection solution that simplifies upgrades and bolsters system reliability without sacrificing space or accessibility.
