Siemens QR22B125 is a 125 A, 2‑pole, 240 V bolt‑on circuit breaker designed to protect panelboards, load centers, and electrical distribution systems with dependable performance. Built for retrofit work and maintenance planning where the part number must stay consistent, it enables smooth swaps and long‑term reliability.

  • Amperage: 125 A
  • Poles: 2
  • Voltage: 240 V
  • Mounting: Bolt‑On
  • Manufacturer: Siemens
  • Part Number: QR22B125

This breaker shines in retrofit projects where existing panel configurations need to stay intact while upgrading protection. The bolt‑on design supports quick, secure installation in compatible Siemens panelboards and load centers, reducing downtime during replacements and ensuring continuity with your current electrical distribution setup.

  • Ideal for retrofit work in existing Siemens bolt‑on systems
  • Useful for planned maintenance where QR22B125 is the specified part
  • Suitable for panelboards and load centers that require solid 125 A protection
  • Fits into standard Siemens electrical distribution configurations for reliable protection

Why choose the QR22B125 for your project? It combines a robust 125‑amp, 2‑pole configuration with a bolt‑on mounting method that supports straightforward installation and consistent part numbering across repairs and upgrades. This helps keep your maintenance plans predictable and your electrical distribution protected without surprises.

Practical tips: - Verify that your panelboard or load center is designed for bolt‑on breakers of Siemens QR series and that QR22B125 matches the required 2‑pole 240 V protection. - Before installation, ensure power is fully shut off, and inspect mounting grounds and bus connections for a clean, secure fit. - If you’re coordinating multiple replacements, align part numbers across your project to simplify ordering and inventory management.
