ITE XP421 - 30A, 250V, 3-Phase, Fusible Bus Plug

Meet the ITE XP421 Fusible Bus Plug—a purpose-built, fuse-protected connection for demanding electrical distributions. Engineered for 3-phase busway and panelboard systems, this device delivers targeted overcurrent protection right at the distribution point, helping to minimize downstream faults and downtime in industrial and commercial environments.

Key benefits and why it matters

• 3-Phase, 30A, 250V performance—provides reliable, fuse-protected power routing for standard industrial loads without oversizing the protection scheme.
• Integrated protection at the distribution point—the fusible design isolates faults quickly, protecting feeders, equipment, and downstream circuitry.
• Plug-in simplicity for busway and panelboards—streamlines upgrades, maintenance, and retrofit projects by offering a compatible, hard-to-find solution in one component.
• Rugged, industry-ready construction—built to withstand the rigors of busy facilities, process equipment rooms, and retrofit environments where reliability is non-negotiable.

Ideal applications and use cases

• Industrial plants requiring dependable, fuse-protected distribution at the point of use
• Commercial facilities undergoing power distribution upgrades or retrofits
• Process equipment setups that demand clean isolation and protection of 3-phase circuits
• Maintenance, repair, and upgrade projects needing compatible, hard-to-find busplugs

What makes the XP421 different

• Designed specifically for busway and panelboard power distribution systems, ensuring a secure fit and reliable protection in standard industrial layouts.
• Explicitly specified for 3-phase applications, aligning with common industrial electrical designs while delivering targeted fusible protection rather than generic, one-size-fits-all components.
