General Electric | AC363RGRI | Fusible Bus Plug | 100A | 3-Pole | 600V

Designed for maintenance, retrofit, and replacement projects, the General Electric AC363RGRI Fusible Bus Plug delivers reliable fault isolation for three‑phase power systems. With a robust 100 A rating, three poles, and a 600 V maximum, this GE‑built fusible bus plug is engineered to integrate seamlessly with compatible GE bus assemblies, helping minimize downtime and keep system performance predictable.

Key specifications

• Amperage: 100 A
• Poles: 3‑Pole
• Voltage rating: 600 V
• Part number: AC363RGRI

Why this fusible bus plug matters

The AC363RGRI is more than a simple replacement part; it’s designed to preserve the integrity of GE bus systems. A genuine GE fusible bus plug ensures mating interfaces align with factory tolerances and current paths, reducing the risk of misfit, overheating, or intermittent contact that can occur with generic substitutes. The result is more predictable performance and smoother maintenance cycles in demanding industrial and commercial environments.

Ideal use cases

• Maintenance of GE panels and switchgear that require a 100 A, 3‑pole fusible bus plug
• Retrofit projects to upgrade or modernize power distribution without changing entire assemblies
• Replacement for worn or damaged bus plugs in three‑phase equipment to restore proper functionality

Installation considerations and practical tips

Before ordering, confirm fit and ratings match your equipment by cross‑referencing the GE part number AC363RGRI with your panel catalog. The 3‑pole configuration is suited to three‑phase installations; ensure your bus interface and spacing align with GE’s specifications. For safe handling, work only with the power fully de‑energized and follow your facility’s lockout/tagout procedures during installation and replacement.

Why choose GE AC363RGRI over alternatives

Choosing a genuine General Electric fusible bus plug guarantees an authentic fit with the corresponding GE bus assemblies, delivering consistent contact reliability and electrical performance. Unlike generic substitutes, this part is purpose‑built for GE systems, reducing compatibility risk and accelerating service windows in maintenance and retrofit projects.

What you can expect in practice

With the AC363RGRI, expect a straightforward replacement experience that restores intended current paths and protects downstream devices at up to 600 V. This ensures your three‑phase distribution remains coordinated, supporting stable operation across feeders and downstream protection devices while supporting efficient, safer electrical work during upgrades or repairs.
