AC321RG - 30A, 240V, 3-Phase, Fusible Bus Plug

Meet the AC321RG Fusible Bus Plug — a purpose-built solution for high-demand power distribution in industrial and commercial settings. With a 30A, 240V, 3-Phase configuration, this plug-in device delivers reliable, controlled power where it’s needed most.

What makes AC321RG stand out

• Precise 30A, 240V 3-Phase capability: designed to handle standard industrial busway and panelboard distributions with clean, balanced three-phase power.
• Fusible protection: quick-disconnect capability that helps isolate faults and protect downstream equipment during abnormal conditions.
• Direct-fit for busway and panelboard systems: specifically engineered as a Fusible Bus Plug for compatible infrastructure, enabling seamless integration in retrofit projects.
• Hard-to-find replacement compatibility: ideal for maintenance, repair, and upgrade efforts where matching busplugs are scarce.
• Industrial-grade reliability: built to endure demanding environments in plants and facilities, supporting ongoing production with dependable power distribution.

Typical applications include industrial plants, commercial facilities, process equipment, and retrofit projects where uninterrupted power distribution is critical. The AC321RG is intended for installations that require a compliant, fusible solution within busway and panelboard architectures.

Why choose this bus plug over generic options

Unlike generic connectors, the AC321RG is purpose-built for 3-phase power systems, ensuring proper phase balance and compatibility with your existing busway or panelboard. Its fusible design provides precise protection for feeders and equipment, reducing the risk of cascading failures and minimizing downtime during maintenance or upgrades.

Practical tips for use:

• Confirm your system’s busway or panelboard compatibility with the AC321RG before installation.
• Keep a spare fusible bus plug on hand for maintenance windows or retrofit campaigns to minimize equipment downtime.
• During installation, follow all safety protocols for high-voltage work and verify correct phase and rating matches to prevent misalignment or misrating.
