Eaton TAP321 - 30A, 240V, 3-Pole Fusible Plug-In Unit for Standard/Low Impedance Busway | AmpState

Eaton TAP321 is a 30A, 240V, 3-pole fusible plug-in unit crafted for Eaton standard plug-in and low impedance busway systems. Designed to protect 240V branch circuits, this module delivers reliable fault interruption while keeping installations modular and upgrade-friendly. Fuses are not included, so you can pair the TAP321 with the exact fuse type your protection strategy requires.

• 3-pole protection cuts power on all three hot conductors to ensure balanced, safe shutdown in the event of a fault.
• Plug-in convenience enables straightforward integration into compatible Eaton busway sections, reducing commissioning time and maintenance downtime.
• Broad compatibility works with both Eaton standard plug-in busways and low impedance busways, supporting compact, scalable distributions in commercial and light industrial settings.
• 30A, 240V rating suits a wide range of branch-circuit applications, from equipment feeds to dedicated subcircuits.
• Fuses not included gives you the flexibility to select the fuse links and time characteristics that best fit your protection plan.

Ideal for electrical contractors, facilities engineers, and maintenance teams who rely on modular busway distributions, the TAP321 provides a dependable, interchangeable protection option within Eaton’s plug-in ecosystem. It’s especially valuable when retrofitting or expanding a 240V distribution run without sacrificing protection or downtime.

Common use scenarios include extending a protected feeder from an existing Eaton busway, powering 240V motor drives, lighting circuits, or dedicated equipment bays. The plug-in design simplifies stock and spares management, helping you speed up both installation and fault-clearance tasks.

Certified for use with Eaton plug-in busway systems and available through AmpState, the TAP321 combines proven protection with practical versatility for modern electrical distributions.
