QB1020GF - 20 Amp Circuit Breaker

QB1020GF - 20 Amp Circuit Breaker

When you're replacing a circuit breaker, getting the details right matters. The QB1020GF is a 20-amp, 1-pole bolt-on circuit breaker rated for 120 VAC, with a 10 kA interrupting rating and built-in 5 mA GFCI protection. Its thermal-magnetic design provides protection against overload and short-circuit conditions, while the GFCI function adds ground-fault protection. At just 1 inch wide, the QB1020GF fits its protection capabilities into a compact package measuring 3.19 inches high by 2.5 inches deep. It's a practical choice for compatible electrical equipment where these exact ratings and a bolt-on connection are required. Before replacing an existing breaker, compare the part number and electrical ratings carefully especially amperage, voltage, pole count, A.I.C. rating, GFCI requirements, and connection style.

Key Features and Benefits

• 20-amp, single-pole design for compatible 120 VAC applications.
• 5 mA GFCI protection provides added protection against ground-fault conditions.
• Thermal-magnetic operation protects against overloads and short circuits.
• Bolt-on connection provides a secure fit in compatible equipment.
• 10 kA A.I.C. at 120 VAC for the specified fault-interruption capability.
• Compact dimensions make it easy to compare against an existing breaker when space and fit are important.
• Clearly identified as Type QB, helping technicians and buyers match the breaker to the requirements of the application.

Material Compliance and Certifications

• Specific certification and material-compliance information was not provided with the available QB1020GF specifications. Any required listings, approvals, or material-compliance standards should be confirmed from the markings on the breaker or the appropriate product documentation before installation. This avoids relying on assumptions when a particular certification is required for a job.

Where It Works Best

• The QB1020GF makes sense when the job calls for a 20A, 1-pole, 120 VAC bolt-on breaker with 5 mA GFCI protection. It can be used for replacement and maintenance applications involving compatible electrical equipment, provided all specifications match.
