AC324RG 200A, 240V, 3-Phase Fusible Bus Plug

The AC324RG Fusible Bus Plug from GE’s Armor-Clad line is a purpose-built solution for rugged 3-phase power distribution. Rated at 200A and operating at 240V, this fusible bus plug is designed to integrate seamlessly into compatible switchgear to deliver reliable, fuse-protected connections between the main bus and individual feeders. Built for reliability in demanding environments, it helps utilities, manufacturers, and facilities teams keep critical loads protected and running smoothly.

Key advantages that set the AC324RG apart

• Precise III-phase protection: Specifically engineered for 3-phase circuits, ensuring balanced protection across all legs of the system.
• Robust Armor-Clad construction: GE’s Armor-Clad lineage emphasizes durability in harsh industrial settings, supporting longer service life and fewer unscheduled outages.
• Modular, plug-in design: Facilitates quick installation, testing, and replacements, minimizing downtime during maintenance or upgrades.
• Clear electrical isolation: Provides a reliable fuse-based disconnect path that helps protect downstream equipment from overcurrent events and simplifies fault isolation.
• Compatibility with GE switchgear: Ideal for new installations or retrofits where a fusible bus plug is the preferred method to add or upgrade feeder protection.

What problems does it solve?

In industrial environments, power disturbances and motor faults can trigger costly downtime. The AC324RG offers:

• Fast, predictable fault interruption on three-phase feeders, helping prevent damage to motors, drives, and downstream controls.
• End-to-end protection that simplifies maintenance planning by allowing selective feeder isolation without full-panel shutdowns.
• A rugged interface that stands up to dust, vibration, and other challenging plant conditions typical of manufacturing floors and process lines.

Ideal use cases

• Upgrading or expanding 3-phase motor control centers (MCCs) and switchgear in manufacturing facilities.
• New installations where a reliable, fuse-based protection path is required for feeders feeding pumps, conveyors, or compressors.
• Retrofits in data centers or critical facilities needing modular, service-friendly protection without complex rewiring.

How it works

The AC324RG sits between the distribution bus and individual feeders. When current exceeds the fuse rating, the fusible elements interrupt the circuit, protecting downstream equipment and enabling safe, controlled disconnection for maintenance. The plug-in design supports straightforward replacement and minimizes exposure to live switching during service events.

Installation and care

• Installation should be performed by a qualified electrician familiar with three-phase switchgear and fusible protection schemes.
• Verify compatibility with your GE panel or bus arrangement and ensure correct fuse type and rating match your protection plan.
• Regularly inspect for signs of overheating, wear on the fuse connections, and physical damage. Replace aging components promptly to maintain protection performance.
