Q2020NC - Duplex 20/20 Circuit Breaker

Q2020NC - Duplex 20/20 Circuit Breaker

Suppose you're replacing a Q2020NC circuit breaker; getting the specifications right matters more than simply finding a breaker that looks the same. The Q2020NC is a 20-amp Type QT duplex circuit breaker rated at 10 kA at 120 VAC. Its duplex layout puts two 20-amp circuits into a breaker that's only 1 inch wide, which can be useful when you're working with limited space in a compatible panel. This is a plug-in circuit breaker measuring 3.13 inches high, 1 inch wide, and 2.56 inches deep. It's also HACR-rated and carries a 40°C rating. That combination makes the Q2020NC a practical replacement or maintenance choice for compatible residential and light-commercial electrical equipment, as well as for qualifying heating, air-conditioning, and refrigeration applications. Before replacing an existing breaker, check the part number and electrical ratings against the panel requirements. Similar-looking breakers aren't necessarily interchangeable.

Material Compliance and Certifications

• The Q2020NC is HACR rated and has a 40°C rating, according to the available specifications. This can be relevant when the breaker is being matched to certain heating, air-conditioning, or refrigeration equipment.
  
  No additional material-compliance or certification claims are made here. If a particular approval or certification is required for your installation, verify it using the breaker labeling and applicable manufacturer documentation.

Where It Works Best

• The Q2020NC makes the most sense in compatible panels designed for Type QT plug-in circuit breakers, particularly when two 20-amp circuits are needed, and panel space is tight. With its duplex configuration, you get two circuits within a 1-inch-wide footprint.
  
  It can be used in appropriate residential or light commercial applications. It may also be used in qualifying HVAC and refrigeration installations where an HACR-rated breaker with these specifications is called for.
