GP-423NA - 100A, 120/208V, 3-Phase, Fusible Bus Plug

The GP-423NA Fusible Bus Plug is engineered for dependable power distribution in environments where reliability matters most. With a 100A rating and a 120/208V, 3-phase configuration, this bus plug integrates cleanly into busway and panelboard systems, delivering targeted protection and streamlined maintenance in industrial and commercial settings.

Why the GP-423NA stands out

• Precise compatibility for demanding systems — specifically designed for busway and panelboard distributions, reducing integration challenges in retrofit projects and ongoing upgrades.
• Hard-to-find, ready-to-use solution — a practical choice for maintenance, repair, and replacement when standard parts are unavailable or out of stock.
• Integrated fusible protection — built-in fusing provides protective isolation at the plug level, helping protect equipment and circuits while simplifying fault isolation.
• 3-city-phase efficiency — 3-Phase configuration supports balanced distribution across loads, improving performance in multi-line industrial equipment and processes.

Ideal applications

• Industrial plants requiring robust, plug-in protection within established power distribution networks
• Commercial facilities upgrading or retrofitting busway or panelboard systems
• Process equipment setups where reliable, modular power distribution is critical
• Retrofit projects that need compatible, readily available bus plugs to minimize downtime
