Eaton | TAP364H | Fusible Bus Plug | 200A | 3-Pole | 600V

Eaton TAP364H Fusible Bus Plug is your reliable solution for protecting three-phase power in 600V systems, designed specifically for maintenance, retrofit, and replacement scenarios. When you need a precise, OEM-aligned component that fits seamlessly into existing Eaton bus assemblies, TAP364H delivers proven performance and quick down-time relief.

• Exact compatibility: The TAP364H designation is the best reference for matching Eaton gear. By choosing the same part number, you minimize installation guesswork and ensure a secure fit within compatible bus layouts.
• Three-pole, 200A protection: With a 200-amp current rating across three poles, this fusible bus plug provides balanced protection for all phases, helping to safeguard feeders and downstream equipment in demanding 3Ø networks.
• 600V system suitability: Engineered for up to 600 volts, it’s suited for industrial and commercial power distribution where higher voltage class protection is required.
• Maintenance-friendly design: Built to simplify servicing, TAP364H supports controlled isolation of circuits during routine maintenance or during planned outages, reducing overall downtime and preserving service continuity for the rest of the panel.
• Retrofit and replacement-ready: Ideal for upgrading aging protection schemes or replacing failed fusible plugs in existing Eaton TAP364H-compatible systems, accelerating project timelines and preserving system reliability.
• Spec-driven reliability: Rely on a component whose ratings and form factor are chosen to align with Eaton’s bus plug architectures, helping ensure robust connections, predictable trip behavior, and long service life when installed per manufacturer guidelines.

How it works in practice: The fusible bus plug sits within a compatible Eaton bus assembly and incorporates fusible elements designed to provide short-circuit protection for a dedicated feeder. In the event of a fault, the fusible link opens, interrupting current flow to the affected circuit while the remaining feeders stay powered, enabling selective protection and minimizing broader system outages. This targeted protection is especially valuable in facilities with multiple critical loads that cannot tolerate a full system shutdown during maintenance.

Who benefits most from this part?

• Electrical maintenance teams upgrading or refurbishing legacy panels that rely on fusible bus plug architectures.
• Facilities managers at manufacturing plants needing reliable, quick-to-service protection during production downtime.
• Data centers, commercial buildings, and industrial sites seeking predictable protection with minimal disruption during service windows.
• Electrical engineers specifying OEM-consistent components to maintain warranty and ensure compatibility with existing switchgear families.

Use cases to consider:

• Retrofit projects where a three-phase protection mechanism must be preserved without reconfiguring entire bus assemblies.
• Routine maintenance programs that require safe, rapid isolation of a single feeder while keeping other circuits energized.
• Replacement of failed or degraded fusible bus plugs in systems designed around Eaton TAP364H specifications.
• New installations within compatible Eaton power distribution schemes that demand a proven, OEM-approved 200A, 3-pole solution.

Compatibility and verification tips (practical guidance):

• Always confirm fit and ratings before ordering. The TAP364H part number is the most reliable reference for compatibility with Eaton bus plug assemblies.
• Verify that your equipment’s bus assembly is rated for 200A and 600V and that a three-pole configuration aligns with your three-phase distribution scheme.
• Consult your existing electrical drawings or Eaton documentation to ensure correct alignment with the specific panel or switchgear family in use.
• Follow all safety protocols during handling, storage, and installation—de-energize the system, wear appropriate PPE, and adhere to lockout/tagout procedures.

Practical installation considerations to maximize performance:

• Install according to the OEM installation instructions, paying attention to enclosure fit, alignment with bus bars, and secure electrical connections.
• Ensure clear labeling of protected circuits and maintain proper documentation for future maintenance or inspections.
• When replacing a plug, verify that other connected feeders remain properly protected and that there is no inadvertent cross-connection during installation.
