Q140H - 40Amp Circuit Breaker

The Q140H is a 40-amp, single-pole Type QPH circuit breaker with a plug-in design and a 22kAIC rating at 120VAC. If you're replacing an existing breaker, the details matter, and this model provides a clear set of specifications to match your equipment. It measures 2.88 inches high, 1 inch wide, and 2.56 inches deep, so it keeps a compact footprint inside compatible electrical equipment. The Q140H is also HACR rated and carries a 40°C rating. That makes it suitable for compatible heating, air-conditioning, refrigeration, and other electrical applications that call for these particular ratings. Rather than choosing a breaker based on amperage alone, check the part number, breaker type, pole count, voltage, interrupting rating, connection style, and dimensions. If your equipment calls for a Q140H 40A 1-pole QPH plug-in circuit breaker, this model meets your specifications.

Key Features and Benefits

  • 40-amp, 1-pole configuration for compatible electrical circuits.
  • 22kAIC at 120VAC provides a 22,000-amp interrupting rating at the specified voltage.
  • Plug-in design for use with compatible equipment designed for this connection style.
  • HACR-rated, making it suitable for applicable heating, air-conditioning, and refrigeration circuits.
  • 40°C rating provides another important specification to check when replacing an existing breaker.
  • At just 1 inch wide, the breaker has a compact profile that works well in panels with limited space.
  • Type QPH identification helps take some of the guesswork out of matching a replacement breaker.

Material Compliance and Certifications

  • Based on the available specifications, the Q140H is HACR-rated and rated at 40°C. No other material-compliance information, environmental certifications, or agency approvals were provided with the product data, so we won't make claims unsupported by the specifications.
  • Electrical compatibility should always be confirmed before installation. Check the requirements for your panel or equipment and ensure the amperage, voltage, pole configuration, A.I.C. rating, breaker type, connection method, and dimensions are correct. Installation should be handled by qualified electrical personnel in accordance with applicable electrical codes and equipment requirements.

Where It Works Best

  • The Q140H circuit breaker is best suited to compatible electrical equipment requiring a 40-amp, single-pole, Type QPH plug-in breaker rated 22kAIC at 120VAC. It's particularly useful when you're replacing an existing breaker and need to match a specific set of electrical and physical characteristics, rather than simply finding one with the same amperage rating.
  • Because it's HACR-rated, the Q140H may also be used in compatible heating, air-conditioning, and refrigeration applications that require a HACR-rated breaker with these specifications.
