Square D | QHB225 | Circuit Breaker | 25A | 2-Pole | 240V | 65kA | Bolt-On

Square D QHB225 is a bolt-on, 2-pole circuit breaker engineered to protect 240V circuits with dependable, trip-responsive performance. Built for maintenance, retrofit, and replacement projects, this 25A unit slots into compatible Square D panelboards with a bolt-on mounting, delivering a solid, code-compliant protection solution when you need it most.

Key specifications

• Amperage: 25A
• Poles: 2-Pole
• Voltage: 240V
• Interrupting capacity: 65 kA
• Mounting type: Bolt-On

What makes this breaker a smart choice

• Reliable bolt-on installation: A secure mechanical connection minimizes vibration and loosening in demanding environments, making it ideal for retrofit or upgrade projects where a rigid fit is essential.
• High fault-current protection: With a 65 kA interrupting rating, it’s designed to safely interrupt substantial fault currents common in commercial and light-industrial applications.
• Precise 25A protection: Provides targeted overcurrent protection for circuits that require firm, consistent current limiting without unnecessary tripping.
• Exact compatibility reference: The part number QHB225 is the best reference for compatibility—always confirm fit and ratings against your panel documentation before ordering.

Ideal use scenarios

• Retrofits in existing Square D bolt-on panels where 25A, 240V protection is required
• Maintenance replacements to restore original protection levels without reconfiguring the panel
• Repairs or upgrades in commercial environments where high fault-current environments demand robust interruption capacity

Installation and compatibility tips

• Always confirm fit and ratings against your panel’s labeling and literature before purchasing.
• Rely on the QHB225 part number as the primary compatibility reference to ensure seamless integration with your bolt-on Square D infrastructure.
• Recognize that this is a bolt-on breaker—designed for panels that specify bolt-on breakers, not plug-on configurations.
• Follow your panel’s installation instructions for torque and conductor sizing to ensure a secure, code-compliant connection.

With the Square D QHB225, you’re choosing a purpose-built, reliable protection device that aligns with legacy bolt-on panel systems while delivering precise 25A, 240V protection and robust 65 kA interrupting capability. It’s the thoughtful retrofit and replacement solution that keeps electrical systems safe, compliant, and ready for the next service interval.
