Eaton TAP325 - 400A, 240V, 3-Pole Fusible Plug-In Unit for Standard/Low Impedance Busway | AmpState

The Eaton TAP325 is a rugged 400A, 240V, 3-pole fusible plug-in unit engineered for seamless integration with Eaton’s standard plug-in and low impedance busways. Specifically designed for 240V branch circuits, this plug-in protection module delivers a modular, serviceable solution that fits cleanly into existing Eaton busway infrastructure. Note: fuses are not included.

Why the TAP325 stands out

• Plug-in simplicity: Tap-in design enables faster installation and easier field maintenance compared to traditional hard-wired fuse blocks, reducing downtime during upgrades or replacements.
• Robust 3-pole protection: Provides balanced protection across all three phases, helping maintain system stability under transient faults and overloads.
• High-current capacity: Rated for up to 400A, making it suitable for demanding 3-phase loads common in industrial and commercial distributions.
• Busway compatibility: Specifically designed for Eaton standard plug-in busways and low impedance busways, ensuring reliable integration within your existing distribution scheme.
• Clear 240V branch circuit focus: Optimized for 240V applications, aligning with common industrial and building infrastructure needs.
• Fuse configuration flexibility: Since fuses are not included, you can source the exact fuse type and rating that matches your protection strategy and maintenance practices.

Ideal applications and use cases

• Industrial facilities with Eaton plug-in busway distributions seeking modular, upgradeable protection for 240V branch circuits.
• Facilities undergoing electrical distribution upgrades where rapid swap-in of protective devices minimizes downtime.
• Maintenance-ready setups that benefit from a plug-in unit you can service without rewiring or extensive downtime.
• Systems that require three-phase protection without altering existing busway layouts, preserving compatibility and utility footprint.

What you gain with TAP325

• Reliable, phase-balanced protection integrated with your Eaton busway network, helping protect downstream equipment and reduce fault-related outages.
• Operational efficiency through simplified installation and service routines, supported by Eaton’s proven busway compatibility.
• Design flexibility by choosing the exact fuse type to match your protection philosophy and maintenance practices (fuses sold separately).
