Q120AF - 20Amp Circuit Breaker

Q120AF - 20Amp Circuit Breaker

Looking for a Q120AF circuit breaker to match an existing application? This 20-amp, 1-pole Type QAF breaker is designed for compatible 120VAC electrical systems and features arc-fault circuit interruption (AFCI). It has a plug-in connection and a 10 kA I.C. rating at 120 VAC, with dimensions of 3.13 inches high, 1 inch wide, and 2.5 inches deep. Those details are especially important when you're working with an existing or legacy panel, where getting the correct breaker isn't simply a matter of matching the amperage. The part number, breaker type, pole count, voltage, connection style, and physical fit all need to line up. The Q120AF is also HACR-rated and carries a 40°C rating. Simply put, this is a breaker intended for applications that call for the Q120AF configuration, and it's built to last when installed and used within its specified ratings.

Key Features and Benefits

• 20-amp, 1-pole design for compatible 120 VAC applications.
• Arc-fault circuit interruption (AFCI) for applications that require this type of protection.
• 10 kA I.C. at 120 VAC provides the breaker's specified interrupting rating.
• Plug-in design makes it suitable for electrical equipment designed around the Type QAF configuration.
• At just 1 inch wide, it maintains the required footprint in compatible panels.
• HACR-rated for applicable installations.
• 40°C, rated per the available product specifications.
• A practical choice when the job calls for the specific form, fit, and function of a Q120AF breaker.

Where It Works Best

• The Q120AF 20-amp AFCI breaker makes the most sense in compatible existing and legacy electrical systems that specifically require this breaker configuration. It's intended for applications calling for a Type QAF, 1-pole, 20-amp, 120VAC plug-in breaker with a 10 kA.I.C. rating.
• Replacing an existing breaker? Check more than the amp rating. Start with the Q120AF part number and Type QAF designation, then verify the voltage, number of poles, A.I.C. rating, connection style, dimensions, and panel compatibility. Two breakers can look similar without being interchangeable, so matching the required specifications is important.
• When the application specifically calls for a Q120AF, this breaker provides the familiar dimensions, electrical ratings, and configuration needed to maintain the system's intended form, fit, and function. Installation should always follow the equipment requirements and applicable electrical codes.
