QB20 - 20 Amp Circuit Breaker

Need a replacement Type QB breaker that matches an existing installation? The QB20 is a 20-amp, single-pole circuit breaker designed for compatible electrical panels that require this specific configuration. Rated at 120VAC with a 10 kA AIC rating, it provides the correct form and fit for applications where maintaining the original breaker specifications matters.

The QB20 measures 4.81 inches high, 0.75 inches wide, and 2.5 inches deep, making it a direct match for installations requiring these dimensions. It is available as either a refurbished factory original unit or a brand-new UB ETL Listed aftermarket replacement. The refurbished version is an original factory breaker prepared for continued service, while the new replacement option is made to fit the same space and serve as a compatible replacement.

When you are working on an existing electrical system, finding a breaker with the right amperage, pole configuration, and physical fit is important. The QB20 helps make that replacement process straightforward by matching the specifications required for compatible Type QB applications.
