Description
Product Overview
The Siemens QF240A Ground Fault Circuit Interrupter (GFCI) is engineered to deliver robust 40 amp double‑pole protection for a wide range of residential and light commercial applications. Constructed from high‑grade copper and reinforced polymer components, this breaker meets and exceeds UL 943 requirements, ensuring reliable performance under demanding electrical loads. With a 10,000 ampere interrupting capacity (AIC), the QF240A can safely clear fault currents without damage to the surrounding wiring or panel. The integrated self‑test feature, mandated by UL standards, automatically verifies the breaker’s functionality each time power is restored, providing continuous assurance that the device will trip when a ground fault is detected. Dimensions of 7 x 2 x 3 inches and a weight of just one pound make the QF240A a compact yet powerful addition to any standard load center. Its double‑pole design simplifies wiring and reduces panel space requirements, while the clear labeling and intuitive toggle lever facilitate quick installation and maintenance.

Usage
Designed for versatility, the QF240A is ideal for protecting circuits in kitchens, bathrooms, garages, outdoor outlets, spas, and hot tubs. In kitchen environments, the breaker safeguards countertop appliances, dishwashers, and refrigeration units against ground‑fault hazards that could otherwise lead to electric shock. Bathroom installations benefit from the breaker’s rapid response to moisture‑induced faults, protecting lighting fixtures, hair dryers, and electric shavers. For spa and hot‑tub owners, the QF240A offers peace of mind by detecting even low‑level leakage currents that can arise from submerged equipment, ensuring user safety while complying with local electrical codes. The breaker’s 40 amp rating also supports high‑draw appliances such as electric ranges, water heaters, and air‑conditioning units, making it a flexible solution for electricians and DIY homeowners alike.
