Q120H - 20Amp Circuit Breaker

Q120H - 20Amp Circuit Breaker

Need a Q120H circuit breaker for a replacement or maintenance job? This 20-amp, 1-pole QPH breaker features a plug-in design and is rated at 10 kAIC at 120 VAC. It measures 2.88 inches high, 1 inch wide, and 2.56 inches deep, so checking it against the breaker you're replacing is straightforward. The Q120H is also HACR-rated and carries a 40°C temperature rating. It's a practical option when your equipment requires this specific combination of amperage, pole configuration, breaker type, and interrupting rating. And that's important—circuit breakers can look very similar while having different electrical characteristics. Before replacing an existing breaker, carefully compare the part number and ratings, and make sure the Q120H is compatible with your equipment.

Key Features and Benefits

• 20-amp rating for applications that specify a 20A breaker.
• Single-pole design for equipment requiring a 1-pole configuration.
• Rated 10kAIC at 120VAC.
• Type QPH configuration makes it easier to identify and match the correct breaker.
• Plug-in design for use with compatible equipment.

Where It Works Best

• The Q120H 20-amp circuit breaker is a good fit for maintenance and replacement applications where the existing electrical equipment specifically requires a 1-pole, Type QPH plug-in breaker rated 10kAIC at 120VAC.
• Replacing an older breaker? Don't rely on appearance alone. Start with the Q120H part number, then compare the amperage, number of poles, voltage, AIC rating, breaker type, connection style, and dimensions. Getting those details right is much more important than simply finding a breaker that looks like the one being replaced.
• For applications that require these exact specifications, the Q120H offers a straightforward 20A, 1-pole plug-in circuit breaker in a compact 1-inch-wide design. Always confirm compatibility with the intended electrical equipment and follow applicable electrical codes and installation requirements.
