The Siemens LGB3B015 Circuit Breaker is a purpose-built protective device for industrial electrical service, maintenance, and replacement projects. This 3-pole breaker delivers reliable overcurrent protection for three-phase systems at 277V, with a 15A rating. Use the part number LGB3B015 to confirm compatibility with your panel and application requirements.

Why the Siemens LGB3B015 stands out for three-phase 277V systems

  • Three-pole protection — safely disconnects all three hot conductors in a 3-phase circuit, reducing imbalance risk and enhancing system safety during fault conditions.
  • 15 amp rating — well-suited for moderate-load industrial circuits, including lighting, control gear, and smaller motor loads within 277V distribution environments.
  • 277V compatibility — designed for equipment and applications that operate on 277V, common in commercial and industrial facilities with 3-phase power.
  • Direct-fit replacement — aligns with Siemens panel configurations, streamlining retrofits and replacements when the LGB3B015 is the required part number.
