Q320H - 20Amp Circuit Breaker

Q320H - 20Amp Circuit Breaker

Need a Q320H circuit breaker and want to confirm the important specs quickly? The Q320H is a 20-amp, 3-pole, Type QPH plug-in circuit breaker rated at 22kA A.I.C. at 240VAC. It's a practical choice for compatible electrical distribution equipment that calls for this specific breaker type, amperage, pole configuration, and interrupting rating. The Q320H measures approximately 3.13 inches high, 3.0 inches wide, and 2.56 inches deep, providing electricians, contractors, and maintenance teams with the physical dimensions they need to check compatibility. It is also HACR-rated and carries a 40°C rating. Whether you're replacing an existing breaker or matching components for electrical maintenance, getting the details right matters. Check the Q320H part number, amperage, poles, voltage, A.I.C. rating, breaker type, dimensions, and plug-in configuration against your equipment requirements before installation.

Key Features and Benefits

• The Q320H provides a 20A rating across a three-pole configuration for compatible electrical applications.
• Offers an interrupting rating of 22,000 amps at 240 VAC, an important specification when matching a breaker to an electrical system's requirements.
• Clearly identified as a Type QPH circuit breaker, making it easier to compare against existing equipment specifications.
• Its plug-in configuration is designed for compatible equipment that accepts this breaker style.
• The Q320H is HACR-rated, an important consideration for compatible HVAC and refrigeration applications that require this designation.
• Rated at 40°C according to the available product specifications.
• Measuring approximately 3.13" H × 3.0" W × 2.56" D, the breaker's dimensions can be checked before installation to help confirm the proper physical fit.
• The combination of the Q320H part number, QPH type, 20A rating, three poles, and 22kA rating makes it easier for professionals to verify the breaker they need.

Material Compliance and Certifications

• The supplied specifications identify the Q320H circuit breaker as HACR rated and specify a 40°C rating. No additional material-compliance declarations, agency listings, or certifications are included in the available product information, so we won't make claims that aren't supported by the specifications. If your project requires a particular certification, material-compliance standard, or regulatory listing, verify those requirements against the appropriate product documentation before installation.
  

Where It Works Best

• The Q320H 20 amp 3-pole circuit breaker is best suited for compatible electrical panels and distribution equipment designed to accept Type QPH plug-in breakers. It's particularly relevant when the application specifically calls for a 20A, three-pole breaker with a 22kA A.I.C. rating at 240VAC. Its HACR rating can also make it suitable for compatible heating, air-conditioning, and refrigeration applications where an HACR-rated breaker is specified.
  For maintenance teams and electrical professionals, the biggest advantage is straightforward specification matching. If the equipment calls for Q320H, Type QPH, 20 amps, three poles, 240VAC, and a 22kA interrupting rating, you can compare those requirements directly with the specifications above instead of guessing based on appearance alone.
