Why this Siemens breaker matters

The 10 kA interrupting rating provides robust protection against fault currents on typical residential circuits, helping reduce potential damage to wiring and connected devices. A 1-pole, 120-volt design is the standard choice for safeguarding individual branch circuits—such as lighting, outlets, or small appliances—while maintaining straightforward replacement in existing panels.

Designed for reliable compatibility

For exact fit and performance, rely on the part number BQ1B010. This breaker is aligned with Siemens’ BQ family specifications, delivering predictable trip characteristics and consistent electrical performance. Before ordering, confirm that your panel or load center lists BQ1B010 as a compatible replacement to prevent mismatches and ensure proper protection.

Ideal use cases

Use this breaker when upgrading a panel, replacing a failed unit, or matching a known 10A load on a branch circuit. It’s particularly well-suited for lighting circuits in living spaces, dedicated appliance outlets, garages, or workshops where dependable protection is essential and the installation relies on a Siemens-branded, wire-compatible component.

Installation and practical tips

• Power down the main before beginning any work on the panel, and test the circuit to confirm no voltage is present.
• Use the appropriate screwdriver and apply torque per your panel’s guidelines to ensure secure connections and reliable tripping.
• Keep the exact part number (BQ1B010) on hand for future replacements to maintain consistent protection across the system.
