Siemens QF250A Ground Fault Circuit Interrupter 50A Double Pole

Description

Product Overview

The Siemens QF250A is a premium Ground Fault Circuit Interrupter (GFCI) designed for residential and light commercial electrical systems. Engineered as a double‑pole, 50 Amp breaker, it delivers a robust 10,000 AIC (Ampere Interrupt Capacity) rating, providing superior fault‑current handling capability. Constructed from high‑grade copper and reinforced polymer housing, the unit meets rigorous UL 943 standards and includes a built‑in self‑test mechanism that continuously verifies operational integrity. Its compact 7 × 2 × 3 inch footprint and lightweight 1‑pound design enable straightforward installation in standard panel boards while maintaining a low profile for space‑constrained applications.

Usage

Designed for versatility, the QF250A excels in environments where water exposure and electrical safety intersect. Ideal for spas, hot tubs, kitchen countertop outlets, bathroom receptacles, and outdoor garden lighting, the breaker safeguards against ground‑fault currents that could otherwise cause electric shock or fire hazards. Its class A GFCI protection ensures rapid trip response, typically within 4–6 milliseconds, protecting users in high‑risk areas such as poolside decks and laundry rooms. The breaker also supports dedicated circuits for high‑draw appliances like electric water heaters and electric vehicle charging stations, making it a reliable choice for modern, energy‑conscious homes.

FAQ

What does the 10,000 AIC rating mean?

The 10,000 AIC (Ampere Interrupt Capacity) rating indicates the breaker’s ability to safely interrupt extremely high fault currents without damage, ensuring reliable protection during severe short‑circuit events.

How does the self‑test feature work?

The built‑in self‑test automatically checks the GFCI mechanism each time power is applied. If a fault is detected, the breaker will trip and display an indicator, alerting the installer to replace or service the unit.

Can this breaker be used for both indoor and outdoor panels?

Yes, the QF250A is rated for indoor and outdoor installations when housed in a weather‑rated panel enclosure, making it suitable for a wide range of residential applications.
