Square D | QO270VH | Circuit Breaker | 2-Pole | 240V | 22kA | Plug-In

Meet the Square D QO270VH, a dependable 2-pole, 240V plug-in circuit breaker designed for precise overcurrent protection in Square D QO panels. Built to handle demanding electrical loads, this unit delivers a robust 22kA interrupting capacity to quickly clear faults and minimize damage to wiring and connected devices.

• Poles: 2-Pole
• Voltage: 240V
• Interrupting rating: 22kA
• Mounting style: Plug-In
• Compatibility reference: Part number QO270VH confirms exact fit for QO-series panels

What makes this breaker stand out is its plug-in design for fast, straightforward swaps during maintenance or retrofit projects, minimizing panel downtime. With a 240V rating, it suits standard branch circuits in residential and light commercial settings, while the 22kA capacity provides a reliable margin against high fault currents typically encountered in shared service environments.

Compatibility notes: Confirm fit and ratings before ordering. The part number is the best reference for ensuring the unit matches your panel model and bus configuration.

• Use case: Maintenance and replacement in existing Square D QO panels without complex rewiring
• Use case: Retrofit when exact 240V, 2-pole protection is required in compatible systems
• Use case: New installations in panels that require a reliable plug-in protection solution

Pro tip for buyers: when selecting this breaker, align it with your panel’s model and protection plan. Replacing an old unit with the same 240V, 22kA specifications helps preserve protective coordination across circuits, keeping your electrical system safer and more reliable.
