Square D | TAP364J | Fusible Bus Plug | 3-Pole | 600V | Plug-In

Square D TAP364J Fusible Bus Plug — a 3-Pole, 600V plug-in bus plug designed for fast, reliable field replacements in compatible Square D switchgear.

Built for maintenance, retrofit, and replacement projects where precise specifications matter, this fusible bus plug enables you to swap in a ready-made protection module without a full panel teardown.

Key features and benefits

• 3-Pole, three-phase configuration: aligns with standard 3-phase distribution, ensuring balanced protection across all phases.
• 600V voltage rating: suitable for typical industrial distribution equipment within this voltage class.
• Plug-In design: simplifies installation and minimizes downtime—often eliminating the need for extensive disassembly.
• Fusible protection: provides controlled disconnection under fault conditions, helping safeguard downstream equipment and conductors.
• Part number TAP364J as the best compatibility reference: verify fit and ratings before ordering to ensure seamless integration.
• Maintenance and retrofit ready: an efficient solution for updating aging infrastructure or swapping in upgraded protection where specs align.

Ideal use cases

• Technical service and maintenance teams performing routine replacements in high- or medium-voltage switchgear compatible with Square D components.
• Retrofit projects when upgrading protection schemes without rebuilding entire bus assemblies.
• Stocking a spare TAP364J for quick field replacements to minimize downtime during outages or repairs.

How to ensure compatibility

Before ordering, confirm fit and ratings for your equipment. The TAP364J designation is the most reliable reference for compatibility with Square D assemblies; if you’re replacing an existing bus plug, compare the part number to ensure identical electrical and mechanical interfaces.

Why this matters

In industrial environments, downtime is costly. The Square D TAP364J Fusible Bus Plug provides a ready-to-install, three-phase protection module that can be swapped in quickly, reducing service interruptions while preserving protective coordination within your system.
