Siemens | BQ1B070H | Circuit Breaker | 1-Pole | 120V | 22kA | Bolt-On

Siemens BQ1B070H is a 1-pole, 120V bolt-on circuit breaker engineered for dependable protection in maintenance, retrofit, and replacement projects where exact specifications matter. The part number BQ1B070H serves as the most reliable reference for compatibility with Siemens bolt-on panels that require a 1-Pole, 120-Volt, 22kA interrupting capacity breaker.

• Poles: 1-Pole
• Voltage: 120V
• Interrupting capacity: 22kA
• Mounting: Bolt-On
• Part reference: BQ1B070H

The 22kA interrupting rating provides robust protection for typical residential and light commercial circuits, helping to guard against high-energy fault conditions. The bolt-on design delivers a secure, vibration-resistant connection, ideal for panels that specify bolt-on breakers rather than plug-on styles.

Use cases include panel maintenance, retrofits, and replacements where your Siemens panel documentation calls for a 1-pole, 120V bolt-on breaker. Always confirm fit and ratings before ordering—the part number is the best reference for compatibility with your specific panel model.

Why choose this Siemens breaker: it’s a manufacturer-matched solution that integrates seamlessly with Siemens protective devices, delivering reliable performance in 120V circuits such as lighting, outlets, or dedicated loads within compatible panels. The compact, straightforward bolt-on mounting simplifies installation in appropriate panels and supports long-term circuit protection.

Practical installation tips: power down the panel, verify that your panel accepts bolt-on breakers, and follow the panel’s torque and installation guidelines. If there’s any uncertainty about compatibility, rely on the exact BQ1B070H reference to minimize compatibility risk and ensure continued electrical protection.
