AC365RG 400A, 480/600V, 3-Phase Fusible Bus Plug

Meet the AC365RG from GE’s Armor-Clad line — a rugged, reliable 400A, 3‑phase fusible bus plug engineered for demanding industrial power distribution. Designed to slip into your three‑phase bus framework, this device delivers precise overcurrent protection at a voltage rating of 480/600V, helping keep critical systems running smoothly while minimizing downtime in the event of a fault.

Why this fusible bus plug matters

• Robust protection for high-demand equipment: The 400A fusible bus plug provides targeted protection for feeders and downstream equipment in switchgear and motor control centers, helping prevent cascading damage from faults.
• Rapid fault isolation: Fusible protection fast-tracks isolation of a faulted phase, reducing arc energy and allowing safe, swift maintenance without taking the entire system offline.
• Durable, industrial-grade construction: Part of GE’s Armor-Clad series, the plug is built to withstand harsh environments, vibration, and temperature variations typical of large facilities and process lines.
