Q2030 - Duplex 20/30 Circuit Breaker

Q2030 - Duplex 20/30 Circuit Breaker

Suppose you're replacing a Q2030 circuit breaker; getting the details right matters. The Q2030 is a Type QT duplex breaker with 20/30-amp ratings, a plug-in connection, and a 10 kA rating at 120 VAC. At only 1 inch wide, it offers two amperage ratings without taking up much space in a compatible panel. That's useful when panel space is already tight. The breaker measures 3.13 inches high, 1 inch wide, and 2.56 inches deep, and is HACR-rated at 40 °C. Before using it as a replacement, compare its specifications with the breaker being replaced and, more importantly, with the panel requirements. Similar-looking breakers aren't always interchangeable.

Key Features and Benefits

• 20/30-amp duplex configuration for applications requiring both amperage ratings.

Material Compliance and Certifications

• The information available for the Q2030 lists it as HACR-rated and 40°C-rated. No additional material-compliance certifications were included in the supplied specifications, so we won't make assumptions about certifications that aren't documented. If your installation has a specific approval or compliance requirement, check that requirement before installation.

Where It Works Best

• This breaker is best suited for compatible electrical panels that accept Type QT plug-in breakers and require a 20/30-Amp duplex configuration. The narrow 1-inch body can be helpful when you're working with limited panel space.
  
  The HACR rating also makes the Q2030 suitable for certain heating, air-conditioning, and refrigeration circuits, provided the equipment calls for a breaker with these specifications.
