Practical tips for successful use

  • Before ordering, confirm fit and ratings by cross-referencing the panel label and equipment documentation. The part number B34500S01 is the best reference for compatibility.
  • Use as a direct replacement when your panel spec calls for a 45A, 3‑pole, 240V Siemens breaker to minimize mismatches and ensure proper protection.
  • Check the panel’s allowed breaker types and the maximum continuous load to avoid overloading the system.
  • Handle with care during replacement—shut off power to the main, verify no voltage presence, and follow standard safety procedures.
