Schneider Electric | PQ3220GR | Fusible Bus Plug | 3-Pole

Schneider Electric PQ3220GR Fusible Bus Plug, a purpose-built 3-Pole protection module designed for maintenance, retrofit, and replacement projects within industrial and commercial electrical panels. This component is engineered to align precisely with Schneider Electric’s bus plug systems, delivering dependable protection while simplifying on-site replacement workflows.

Key benefits that matter in the field

• 3-Pole configuration supports balanced three‑phase power distribution, making it suitable for multi‑phase panel layouts.
• Fusible design provides integrated protection at the bus level, helping isolate faults and protect downstream equipment during servicing or upgrades.
• Part number PQ3220GR serves as the definitive reference for compatibility, ensuring you match the exact specifications when sourcing spare parts.
• Ideal for maintenance, retrofit, and replacement scenarios where exact specs and reliable performance are required.
• Backed by Schneider Electric’s legacy of quality and serviceability, aiding long-term reliability in critical power systems.

Why this matters for your project

In environments where downtime is costly, the PQ3220GR fusible bus plug offers a targeted, compatible solution to keep three‑phase systems protected while you service or upgrade switchgear. The 3‑pole design aligns with common three‑phase panel configurations, reducing guesswork during planning and installation. By using the exact part identifier PQ3220GR, technicians can quickly verify fit and ratings, accelerating procurement and minimizing risk of mismatches.

Compatibility and installation considerations

Before ordering, confirm fit and ratings by referencing the PQ3220GR part number as your primary compatibility check. This ensures the bus plug matches the electrical characteristics and mounting interface of your Schneider Electric panels. Use this component in systems that specify fusible bus plugs of the relevant family and where a 3‑pole configuration is required. Always follow standard electrical safety practices and the panel manufacturer’s installation guidelines when integrating a fusible bus plug.

Use cases

• Maintenance outages: swap in the PQ3220GR to restore protected bus paths with minimal panel disruption.
• Retrofits: upgrade aging or non-fusible bus configurations to a fusible plug for enhanced fault isolation.
• Replacement parts: maintain a ready spare to reduce downtime during critical service windows.

Practical tips for installers

• Ensure power is fully de-energized and follow lockout/tagout procedures before handling any bus plug components.
• Inspect the surrounding bus interface and mounting points for cleanliness and any signs of corrosion or wear prior to installation.
• Keep a documented inventory of part numbers and corresponding panel models to streamline future service calls.
• Coordinate with your panel’s documented fuse ratings and protection scheme to maintain consistent protective coverage after replacement.
