Meet the Siemens LGB1K015B circuit breaker — a purpose-built, bolt-on solution designed for 347V circuits that protects your critical electrical loads with precision. With a 15A rating and a single-pole configuration, this breaker is crafted for maintenance, retrofit, and replacement tasks where exact compatibility matters. The LGB1K015B isn’t a generic part; it’s a direct-fit option that aligns with Siemens panel systems and the specific form factor your setup requires.

Key specifications

• Amperage: 15A
• Poles: 1-Pole
• Voltage rating: 347V
• Mounting: Bolt-On
• Part number: LGB1K015B

Why this breaker stands out

• Exact compatibility: The LGB1K015B is the precise replacement for Siemens panels that require this bolt-on, 1-pole configuration—use the part number as your best compatibility reference.
• Secure bolt-on mounting: Designed for reliable, vibration-resistant installation in demanding environments, helping maintain consistent electrical protection over time.
• Targeted protection: With a 15A rating, it’s ideal for protecting branch circuits that don’t need higher amperage while ensuring quick, predictable interruption on fault conditions.
• Versatile for modernizations: An excellent choice for maintenance, retrofit, and replacement projects where upgrading or matching older Siemens gear is essential.

Ideal use cases

• Maintaining or renewing Siemens panelboard circuits that require a bolt-on, 1-pole breaker with 347V operating capability.
• Retrofit projects in commercial or light industrial settings where 347V distribution is present and a precise Siemens-compatible solution is needed.
• Spare-part planning for technicians performing on-site service, ensuring quick, reliable replacements during routine maintenance.

Installation and compatibility guidance

Before ordering, verify fit and ratings against your existing equipment. The part number LGB1K015B is the most reliable reference for compatibility with Siemens panels. Look for a bolt-on style, 1-pole, 347V rating in your panel labeling and ensure the overall circuit protection needs match a 15A breaker. If your system requires a direct Siemens replacement in the LGB1K family, this breaker is purpose-built to integrate without modification.

In practice, technicians use this breaker to restore reliable protection quickly during routine maintenance, or to modernize legacy installations where panel requirements specify a bolt-on, single-pole, 347V solution. Expect straightforward installation, aligned with standard electrical safety practices and panel-specific torque and connection guidelines provided by Siemens in your service manuals.
