Square D QBA32225 225A 3P 240V Circuit Breaker, Plug-On | AmpState

Engineered by Square D, the QBA32225 is a rugged 225 A, 3-pole, 240 V circuit breaker designed to deliver dependable overcurrent protection in panelboards, load centers, and electrical distribution systems. With a plug-on design, it enables swift, tool-free installation in compatible panels, helping you minimize downtime during service and replacement projects.

This part is ideal for replacement scenarios and stocking spares to keep your bill of materials aligned with the original part number. By matching the exact QBA32225 specification, you preserve electrical compatibility and system behavior across your distribution network.

• Part number: QBA32225
• Manufacturer: Square D
• Amperage: 225 A
• Poles: 3
• Voltage: 240 V
• Type: Plug-On circuit breaker

Who benefits most: facilities engineers, electricians, and maintenance teams responsible for commercial buildings, manufacturing environments, data centers, and any installation that relies on stable, predictable protection for feeders and distribution circuits. If you’re maintaining legacy panels or aligning new work with existing specifications, this breaker ensures consistent performance and electrical protection.

Why this matters in real-world terms: a properly matched 225 A, 3P, 240 V plug-on breaker helps prevent nuisance trips on normal loads while reliably interrupting fault currents. The plug-on format reduces installation time and equipment handling, which is especially valuable during panel upgrades, retrofits, or when restoring service after a fault. Keeping an exact BOM-aligned part like QBA32225 minimizes change management and inventory complexity.

Practical use cases:

• Replacing a failed breaker in an existing panel with an exact part to maintain electrical characteristics and trip behavior.
• stocking a spare to ensure rapid downtime recovery for critical feeder circuits.
• projects where BOM integrity and part-number traceability are essential for maintenance records and compliance.

Compatibility and guidance: this plug-on breaker is intended for use in panels that accept Square D plug-on devices and are designed for QBA-series protection. If you’re unsure about fit, AmpState can help confirm compatibility by cross-checking the part number against your panel’s BOM. Need help matching a part number or confirming compatibility?
