Siemens Q120 20A 1P 120V Circuit Breaker, Plug-On from AmpState is a precise, plug-on circuit protection device designed for panelboards, load centers, and electrical distribution systems. This 20-amp, single-pole breaker delivers reliable protection where a direct part-number match matters, making it a smart choice for both ongoing maintenance and new-build installations.

Why the Siemens Q120 stands out

The plug-on installation offers quick, secure mounting on compatible bus bars, helping technicians reduce setup time and minimize wiring errors. With a focus on exact compatibility, the Q120 is especially valuable for teams that rely on predictable, field-ready replacements that slot into existing Siemens-equipped panels without modification.

Ideal use cases

  • Maintenance and repairs in service panels where a precise Siemens part-number match is required.
  • Panel construction or retrofits where a direct-fit, 20 A, 1-pole, 120 V breaker is needed.
  • Spare inventory for quick response to tripped circuits, reducing downtime and service interruptions.
  • Electrical distribution setups that rely on plug-on protection for fast commissioning and easy future upgrades.
