Siemens QF240A - 40A, 2-Pole, GFCI Ground-Fault Circuit Breaker

Meet the Siemens QF240A—a robust 40A, 2-Pole GFCI Ground-Fault Circuit Breaker designed for demanding electrical environments. Built to protect people and equipment, it delivers dependable overcurrent protection with fast ground-fault response in distribution panels, motor control centers, and control panels.

What makes this GFCI breaker stand out

• Precise ground-fault protection: Integrated GFCI functionality detects leakage to ground and promptly interrupts power to reduce shock risk and prevent equipment damage.
• 2-Pole configuration: Simultaneously disconnects both conductors on multi-wire circuits, providing safer, more predictable protection and minimizing nuisance trips.
• Versatile deployment: Specifically designed for flexible use in panelboards, switchboards, and control panels across industrial, commercial, and OEM applications.
• Proven Siemens reliability: Part of a trusted lineup known for long-term safety and consistent performance in distribution and motor control environments.

Ideal use scenarios

Engineered for environments where safety and reliability are non-negotiable. Ideal for manufacturing lines, process equipment, HVAC control panels, and other machinery control centers. Suitable for new installations and upgrades that require dedicated ground-fault protection without compromising system continuity.
