Eaton TAP326 - 600A, 240V, 3-Pole Fusible Plug-In Unit for Standard/Low Impedance Busway | AmpState

The Eaton TAP326 is a robust 600A, 240V, 3-pole fusible plug-in unit designed for use with Eaton standard plug-in and low impedance busways. Built to protect 240V branch circuits, this plug-in unit delivers reliable fault interruption when paired with the appropriate fuse links (fuses not included). It integrates smoothly into existing busway infrastructure, helping you maintain clean, organized power distribution with minimal downtime.

Why engineers choose the TAP326

• Plug-in simplicity: Quick installation and straightforward maintenance within Eaton busway systems, reducing downtime during routine service or upgrades.
• Three-phase protection: 3-pole design provides balanced protection across all phases, enhancing overall system reliability.
• High current capability: 600A rating makes it suitable for substantial 240V branch circuits and motor loads often found in manufacturing, facilities, and process environments.
• Busway compatibility: Specifically engineered for Eaton standard plug-in and low impedance busways, minimizing the need for incompatible adapters or extensive rewiring.
• Fuses sourced separately: Fuses are not included, giving you the flexibility to select the exact fuse type and rating that matches your protection scheme and coordination requirements.

Ideal applications and use cases

• Industrial facilities and manufacturing lines where 240V equipment runs on a three-phase distribution network.
• Motor drives, pumps, and other heavy loads that require reliable, modular branch circuit protection integrated into busway systems.
• Facilities upgrading existing Eaton plug-in or low impedance busways with a robust, easily replaceable fusible protection stage.

Technical essentials

• Current rating: 600A
• Voltage: 240V
• Poles: 3-pole
• Busway compatibility: Eaton standard plug-in and low impedance busways
• Fuses included? No — fuses must be purchased separately to complete the protection circuit

Installation and care tips

Ensure you select the correct fuse links to match your system’s protection coordination. Have a qualified electrical professional perform installation to verify proper alignment with your busway configuration and to coordinate upstream protection. The TAP326 is designed to slot into compatible Eaton busways with minimal modification, helping you maintain a clean, scalable distribution network.
