Q3020 - Duplex 30/20 Circuit Breaker

Q3020 - Duplex 30/20 Circuit Breaker

Need a Q3020 circuit breaker for a compatible electrical panel? The Q3020 Type QT 30/20 Amp duplex circuit breaker gives you two branch-circuit amperage ratings in one compact, space-saving design. With a 30-amp circuit and a 20-amp circuit combined in a 1-inch-wide duplex configuration, it’s a practical choice when panel space is limited, and the load center is specifically designed to accept Type QT breakers. The Q3020 is rated for 120VAC operation with a 10kA (10,000-amp) interrupting capacity and features a convenient plug-in design. It’s also HACR-rated, making it suitable for compatible heating, air-conditioning, and refrigeration applications when the equipment and panel specifications call for this breaker type. Measuring approximately 3.13 inches high, 1 inch wide, and 2.56 inches deep, this breaker packs two independent circuit ratings into a compact footprint. Whether you’re replacing an existing Q3020 or matching a breaker to an approved application, checking the part number, Type QT designation, amperage, voltage, and panel compatibility first can help you find the right fit with confidence.

Key Features and Benefits

• The Q3020 combines 30-amp and 20-amp protection in a duplex configuration, helping you make efficient use of available panel space.
• Need to conserve room in a compatible load center? Its duplex design provides two independent breaker poles without requiring the width of two standard full-size breakers.
• Provides a 10,000-amp interrupting capacity at 120VAC for applications that meet its electrical specifications.
• The plug-in configuration is designed for straightforward installation in load centers specifically approved for Type QT breakers.
• Suitable for compatible heating, air-conditioning, and refrigeration applications where an HACR-rated breaker with these specifications is required.
• Part number Q3020, Type QT, and the 30/20-amp configuration make matching an existing breaker or specified replacement easier.

Material Compliance and Certifications

• The Q3020 Type QT circuit breaker is HACR rated and carries a 10kA A.I.C. rating at 120VAC, with the supplied specifications also identifying a 40°C temperature reference. These ratings make it easier to compare the Q3020 with the requirements of the intended electrical system or replacement application. Because circuit breakers are safety-critical electrical components, compatibility matters just as much as amperage or physical size. Always confirm that the electrical panel or load center is specifically listed or labeled for the required breaker type and ratings. A breaker that physically fits a panel is not necessarily approved for use in that panel.
  

Where It Works Best

• The Q3020 30/20 Amp duplex breaker is a strong fit for residential and light commercial electrical systems using a load center specifically approved for Type QT duplex circuit breakers. Its biggest advantage is simple: it saves panel space. By providing separate 30-amp and 20-amp circuit protection within one compact 1-inch-wide assembly, the Q3020 can be especially useful in compatible panels where available breaker positions are at a premium.
