QA120AFC - 20Amp Circuit Breaker

QA120AFC - 20Amp Circuit Breaker

When you’re replacing or matching a circuit breaker, the details matter. The QA120AFC circuit breaker is a 20-amp, 1-pole, 120VAC plug-in breaker with Arc Fault Circuit Interruption (AFCI) designed for compatible electrical panels. Along with standard overcurrent protection, its AFCI functionality helps detect potentially hazardous electrical arcing and interrupt the circuit when an arc-fault condition is detected. The QA120AFC carries a 10 kA interrupting rating at 120 VAC and features a space-efficient 1-inch-wide plug-in design. It is also HACR rated and specified for a 40°C ambient temperature. Whether you’re replacing an existing QA120AFC or looking for a Type QAF breaker with matching electrical specifications, checking the part number, amperage, voltage, pole count, and panel compatibility can help you choose the right breaker with confidence.

Key Features and Benefits

• 20-amp, 1-pole protection designed for compatible 20A, 120VAC branch-circuit applications.
• AFCI functionality helps identify potentially dangerous electrical arcing conditions and interrupt the affected circuit.
• Rated to interrupt up to 10kA at 120VAC under its specified conditions.
• Convenient plug-in configuration designed for installation in compatible load centers and panelboards that accept this breaker type.
• At just 1 inch wide, the QA120AFC occupies a single breaker position in compatible equipment.
• Suitable for applications calling for an HACR-rated breaker when the remaining electrical requirements are satisfied.
• Designed for operation according to its specified 40°C ambient rating.
• The clearly defined 20A, 1-pole, 120VAC, and Type QAF characteristics make it easier to compare against an existing breaker or project requirements.

Material Compliance and Certifications

• The QA120AFC is UL Listed and HACR rated, supporting its use in appropriate applications when installed in compatible equipment and in accordance with applicable electrical requirements. Because circuit breakers are safety-critical components, matching the breaker to the electrical system is important. Always verify the QA120AFC part number, Type QAF designation, 20A rating, 1-pole configuration, 120VAC rating, interrupting capacity, and panel compatibility before installation.

Where It Works Best

• The QA120AFC 20-amp AFCI circuit breaker is a practical choice for compatible residential and light-commercial electrical systems that require a 1-pole, 20A, 120VAC plug-in arc-fault breaker. It is especially useful when replacing a breaker with the same specifications or when a compatible panel calls for a Type QAF AFCI breaker.
