This bus plug is engineered to pair seamlessly with compatible Square D panels and hardware, delivering reliable, field-serviceable connections when you need them most.

Key specifications

• Amperage: 20A
• Poles: 3-Pole
• Voltage rating: 600V
• Part number: PFA36020G
• Brand: Square D

What sets it apart

Unlike generic connectors, the PFA36020G is designed to match Square D’s bus interface exactly, ensuring precise alignment, secure mating, and consistent performance in 3‑pole, 600V applications. The 3-pole configuration supports typical three-phase or multi-conductor arrangements found in industrial control panels, providing a clean, organized power path with reduced risk of resistance or arcing due to improper fit.

Ideal use cases

• Maintenance and service on existing Square D installations where a like-for-like replacement is essential for reliability.
• Retrofit projects that require updating bus connections without replacing the entire panel or bus assembly.
• New equipment builds where a proven, compatible bus plug simplifies installation and support.

Compatibility and best practices

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility, so match PFA36020G to your panel’s bus interface and 600V class. When in doubt, verify the plug’s polarity and alignment with the corresponding bus bars to ensure a secure, stable connection.

Installation and safety tips

• Always disconnect power before handling or installing the bus plug.
• Inspect mating surfaces for damage, debris, or corrosion prior to connection.
• Use appropriate PPE and follow your facility’s safety protocols and local electrical codes.
• Ensure proper orientation and seating to prevent arcing and maintain a reliable electrical path.

Why choose this bus plug

For engineers and technicians who prioritize compatibility, predictability, and ease of maintenance, the Square D PFA36020G provides a dependable, field-friendly solution for 600V systems at 20A. It’s designed to stay within the same family of components, simplifying spare parts management and reducing commissioning risk in both retrofit projects and routine replacement scenarios.
