Square D SD-9454 - 200A, 240V, 3-Phase, Fusible Bus Plug

The Square D SD-9454 Fusible Bus Plug delivers focused, reliable power distribution for demanding industrial and commercial environments. With a 200A rating at 240V in a 3-phase configuration, this bus plug is built to meet the needs of modern facilities while fitting seamlessly into existing busway and panelboard layouts.

What makes this fusible bus plug stand out

• Precise electrical performance — 200A current capacity and 240V operation support balanced, efficient 3‑phase power delivery across demanding loads.
• Integrated fusible protection — built-in fuses interrupt fault currents at the source, helping protect downstream equipment and aiding coordination with upstream protection devices.
• Reliable Square D engineering — designed to endure busy industrial and commercial environments, delivering consistent performance over time.
• Retrofit-ready and maintenance-friendly — an ideal choice for replacement in hard-to-find busplugs, simplifying upgrades and reducing downtime during service windows.
• Versatile application — purpose-built for busway and panelboard power distribution systems, making it suitable for both new installations and refurbishments in a range of facilities.

Ideal use scenarios

• Maintenance, repair, and upgrade projects where compatible, hard-to-find busplugs are required to keep systems running smoothly.
• Industrial plants and process equipment installations that demand robust 3-phase power with protective interruption capabilities.
• Commercial facilities undergoing capacity additions or retrofits, ensuring seamless integration with existing busway or panelboard infrastructure.

Practical considerations and tips

• Verify compatibility with your specific busway or panelboard configuration to ensure a smooth fit and optimal protection.
• Plan protection coordination upstream of the bus plug to achieve selective tripping and minimize downtime during faults.
• In retrofit projects, the SD-9454 can reduce lead times by providing a readily available, compatible fusible option when replacing obsolete or scarce bus plugs.
• Always follow proper lockout/tagout procedures and engage a licensed electrician for installation or replacement in live systems.
