Q20 - 20 Amp Circuit Breaker

Q20 - 20 Amp Circuit Breaker

Suppose you’re replacing a Q20 circuit breaker in existing equipment; getting the details right matters. This 20-amp, 1-pole Type Q breaker has a plug-on design and uses thermal-magnetic operation for overcurrent and short-circuit protection. It is rated 10k AIC at 120VAC and measures 4.81 inches high, 0.75 inches wide, and 2.5 inches deep. Those specifications are especially important when you’re working with legacy electrical equipment, where the breaker needs to match the existing application rather than simply match the amperage. The Q20 is a practical choice for maintenance and replacement work when your equipment requires this Type Q configuration. It’s built to last and designed to do a specific job without unnecessary complexity. Before installation, compare the breaker type, dimensions, pole count, amperage, voltage, AIC rating, and plug-on connection with the requirements of your equipment.

Key Features and Benefits

• 20-amp rating for compatible 20A applications.
• Single-pole design for equipment requiring a 1-pole breaker.
• Rated 10 kA at 120VAC.
• Thermal-magnetic operation provides overcurrent and short-circuit protection within the breaker’s specified ratings.
• Plug-on configuration for compatible electrical equipment.
• At only 0.75 inches wide, it maintains the physical profile required by applicable Type Q installations.
• Well suited to maintenance work where matching the existing breaker’s form, fit, and function is the priority.
• Built to last when properly selected, installed, and used within its stated ratings.

Material Compliance and Certifications

• Specific certification, agency listing, and material compliance information is not included in the available product specifications, so it’s best not to make assumptions about those details. If your application requires a particular listing, certification, or material standard, check the markings on the breaker and the requirements of the equipment where it will be installed.
  As with any circuit breaker replacement, matching amperage alone isn’t enough. The breaker type, voltage, AIC rating, number of poles, connection style, physical fit, and equipment requirements should all be confirmed before installation.

Where It Works Best

• The Q20 20-amp circuit breaker is intended for compatible electrical equipment that calls for a Type Q, 1-pole, plug-on thermal-magnetic breaker with a 10k AIC rating at 120VAC.
  It’s a natural fit for electricians, maintenance departments, and facility teams working on established or legacy electrical systems where keeping the correct breaker configuration is important. In these applications, the goal is simple: match the breaker to the equipment and maintain the required form, fit, and function.
