Siemens QPF120 - 20A, 1-Pole, GFCI Ground-Fault Circuit Breaker

Introducing the Siemens QPF120—a 20A, 1-Pole GFCI Ground-Fault Circuit Breaker designed to elevate safety and reliability in demanding electrical systems. This compact, single-pole unit is built for flexible integration in panelboards, switchboards, and control panels, delivering immediate response to ground faults while providing dependable overcurrent protection.

Why the QPF120 stands out

• 20A protection for standard branch circuits: precisely suited for a wide range of loads in industrial, commercial, and OEM installations.
• 1-Pole configuration for flexible panel layouts: streamlined form factor that fits where space is at a premium in distribution panels and motor control centers.
• GFCI safety you can trust: dedicated ground-fault protection that interrupts power when an imbalance is detected, reducing shock risk for personnel and guarding equipment.
• Siemens engineering and compatibility: purpose-built to integrate with Siemens panelboards, switchboards, and control panels, helping streamline installation and maintenance.
• Durable performance for demanding environments: designed to withstand the rigors of industrial and commercial applications where reliable protection matters most.

Ideal applications

The Siemens QPF120 is a smart choice for industrial facilities, commercial distribution setups, and OEM equipment where robust ground-fault protection and dependable overcurrent protection are essential. Use cases include protecting individual feeders and circuits within panelboards, safeguarding control circuits in switchboards, and reinforcing safety in motor control centers where fast fault interruption is critical.

What to expect in your system

• Ground-fault interruption: detects leakage currents to ground and promptly disconnects the circuit to minimize risk and damage.
• 20A, 1-Pole design: balances protection with a compact footprint for streamlined panel design.
• Targeted protection for critical circuits: helps ensure safer operation of distribution panels and motor control infrastructure.
