Q3030 Duplex 30/30 Circuit Breaker

Q3030 Duplex 30/30 Circuit Breaker

Need two 30-amp circuits but want to make smart use of the available space in your electrical panel? The Q3030 circuit breaker delivers two independent 30-amp circuits in a compact Type QT duplex design. Rated at 30/30 amps, this plug-in circuit breaker has a 10k AIC rating at 120VAC, providing clear electrical specifications for matching a replacement breaker or planning a compatible installation. Its duplex configuration is especially useful when panel space is at a premium, combining two breaker positions into a compact 1-inch-wide unit. At approximately 3.13 inches high, 1.0 inch wide, and 2.56 inches deep, the Q3030 maintains a small footprint while providing the circuit protection required for suitable 30-amp applications. It is also HACR-rated and rated at 40°C, making it suitable for qualifying heating, air-conditioning, and refrigeration applications as well as other compatible branch circuits. If you're replacing an existing Q3030 or matching a breaker to a compatible Type QT panel, checking the part number, amperage, voltage, AIC rating, and breaker type can help ensure you've got the right fit before installation.

Key Features and Benefits

• The 30/30 amp duplex configuration provides two independent 30-amp circuits while making efficient use of panel space.
• At just 1 inch wide, the Q3030 is a practical choice when space inside a compatible electrical panel is limited.
• Provides a 10,000-amp interrupting rating at 120 volts AC for applications within its specified electrical ratings.
• Designed for use with compatible panels and load centers that accept Type QT plug-in breakers.
• Suitable for qualifying heating, air-conditioning, and refrigeration applications when the complete installation meets applicable requirements.
• Designed around the specified 40°C temperature rating.
• The Q3030 part number and 30/30-amp configuration make it easier to compare with existing breaker or panel requirements.
