Siemens BF120A 20A 1P 120V GFCI Bolt-On Circuit Breaker is engineered for everyday electrical protection in panelboards, load centers, and electrical distribution systems. With a 20‑amp, 1‑pole design, this unit provides reliable shutoff and ground-fault protection where you need it most.

Key benefits:

  • Ground-fault protection (GFCI) safeguards people and equipment by interrupting current when a ground fault is detected, making it ideal for kitchens, bathrooms, outdoors, and damp locations.
  • Bolt-On mounting simplifies installation in compatible Siemens panelboards and load centers, helping you achieve a secure, code-compliant connection.
  • Standard 120V, 20A, 1-pole configuration suits a wide range of branch circuits that require dependable overcurrent and ground-fault protection.
  • Original BOM-aligned replacement by using part BF120A promotes seamless BOM consistency in multi-line assemblies and service upgrades.
  • Designed for replacement projects and stocking spares to minimize downtime and keep electrical distribution running smoothly.

Where it fits in your system:

  • Panelboards, load centers, and electrical distribution panels that support bolt-on GFCI breakers
  • Replacement scenarios where maintaining the original part number is important for BOM accuracy
  • Maintenance stock for quick swaps during routine service, reducing project delays

Why choose this BF120A over other options? Siemens builds strong, field-proven protection with predictable trip characteristics and compatibility with standard Siemens accessories. The 1-pole, 20A rating covers common lighting and receptacle circuits while delivering reliable ground-fault protection for damp environments and wet locations where GFCI is required.
