Westinghouse 454D - 60A, 600V, Fusible Bus Plug

The Westinghouse 454D Fusible Bus Plug delivers dependable overcurrent protection and streamlined power distribution for demanding industrial and commercial environments. With a 60A current rating and 600V maximum voltage, this plug-in solution is engineered to integrate smoothly with busway and panelboard systems, enabling modular upgrades and reliable fault interruption where you need it most.

Why the 454D stands out

• Precise electrical protection — a fusible bus plug designed to deliver protective functionality directly at the distribution point, helping to isolate faults quickly and minimize downstream equipment impact.
• High compatibility — manufactured by Westinghouse to align with existing Westinghouse busway infrastructure and other compatible systems, reducing installation guesswork during upgrades or retrofit projects.
• Mid-range power readiness — rated for 60A at up to 600V, making it suitable for mid-sized industrial loads, commercial facilities, and process equipment that require dependable, plug-in protection.
• Strategic for maintenance and upgrades — an ideal solution for maintenance, repair, and upgrade projects where compatible, hard-to-find busplugs are needed to keep facilities running smoothly.
• Efficient installation — the plug-in design supports faster deployment in existing busway runs, helping reduce downtime during service or expansion work.

Ideal use scenarios

• Industrial plants and manufacturing lines that rely on robust busway and panelboard distribution networks.
• Commercial facilities undergoing power distribution upgrades or retrofits to add fused protection at critical distribution points.
• Process equipment environments where reliable, maintainable protection devices are essential for uptime and safety.
• Maintenance teams seeking compatible, readily available busplugs to standardize spares and repairs across sites.
