AC423RG 100A, 240V, 3-Phase, 4-Wire Fusible Bus Plug

Introducing the AC423RG: a 100A, 240V, 3-Phase, 4-Wire Fusible Bus Plug from GE’s Armor-Clad family. Designed to protect and simplify three-phase power distribution, this rugged fusible bus plug slots into your panel or switchgear to deliver fast, reliable protection exactly where you need it.

Why this matters in real-world electrical setups: industrial environments demand dependable overload protection that minimizes downtime and protects downstream equipment. The AC423RG combines precise current rating with a robust enclosure, so you get consistent performance in demanding conditions—from bustling manufacturing floors to large HVAC or pump systems.

• Amp rating: 100A, providing clear, predictable protection for 3-phase loads
• Voltage and phase: 240V, 3-Phase, 4-Wire configuration to support common industrial motor and control circuits
• Type: Fusible bus plug for easy fusing and quick isolation during faults
• Series: Armor-Clad, GE’s rugged line engineered for durability in harsh environments
• Manufacturer: GE, ensuring compatibility with GE distribution components and field service networks

Key benefits that matter in practice

• Fast fault isolation minimizes downtime by reliably opening under overcurrent conditions, protecting motors, drives, and downstream wiring.
• Rugged Armor-Clad housing resists impact, dust, and moisture, extending life in industrial plants and outdoor installations.
• 3-Phase, 4-Wire compatibility supports modern equipment like variable-frequency drives, large motors, and complex control circuits without reconfiguring your setup.
• Modular integration simplifies retrofits and upgrades in existing switchgear, reducing installation time and maintenance headaches.
• GE alignment ensures straightforward sourcing, field service, and compatibility with other Armor-Clad components you may already rely on.

Ideal applications

• Industrial manufacturing lines with heavy motor loads and frequent start/stop cycles
• Large HVAC or pumping systems requiring reliable protection for 3-phase motors
• Machine control panels and switchgear where durable, maintenance-friendly protection is essential
• Data-center or facility distribution rails that rely on robust, wired protection in a 240V, 3-phase environment

Practical guidance for use

• Confirm your system is a 240V, 3-Phase, 4-Wire arrangement before installation
• Replace fusible elements with the same 100A rating to preserve protection integrity
• Follow GE's installation instructions for mounting, wiring sequence, and safety clearances
• Keep spare fuses on hand and schedule periodic inspections of the Armor-Clad assembly to ensure seals and contacts remain intact

The AC423RG Fusible Bus Plug delivers targeted, dependable protection for critical 3-phase loads while leveraging GE’s trusted Armor-Clad durability. It’s a strategic choice for engineers and maintenance teams seeking reliable overload protection, straightforward integration, and long-term resilience in demanding industrial environments.
