QBHW1040 - 40 Amp Circuit Breaker

QBHW1040 - 40 Amp Circuit Breaker

The QBHW1040 is a 40-amp, single-pole bolt-on circuit breaker with thermal-magnetic protection. It is a Type QBHW breaker rated at 22kA at 120VAC and HACR-rated. If you're replacing an existing breaker, those details are worth checking carefully. A breaker with the same amperage isn't necessarily the same breaker.

This unit measures 3.41 inches high, 1 inch wide, and 2.92 inches deep. Its bolt-on connection is intended for compatible electrical equipment designed around the QBHW breaker type. Thermal-magnetic operation protects against both overload and short-circuit conditions.

For HVAC-related work, the QBHW1040 carries an HACR rating for compatible heating, air conditioning, and refrigeration applications. It also has a 40°C rating. Before using it as a replacement, compare the part number and ratings on the existing breaker with the requirements of the panel or other equipment. In particular, check the pole count, amperage, voltage, interrupting rating, and mounting configuration.

Material Compliance and Certifications

• The information available for the QBHW1040 circuit breaker identifies it as HACR-rated and specifies a 40°C rating. No other material-compliance certifications or agency listings are included in the supplied specifications, so no additional certifications should be assumed.
• If a particular listing, approval, or material standard is required for the job, verify that information from the breaker markings and applicable product documentation.
  

Where It Works Best

• The QBHW1040 is a good match when the existing equipment specifically calls for a 40-amp, 1-pole QBHW bolt-on circuit breaker with a 22kA rating at 120VAC. This can include compatible commercial electrical distribution equipment, as well as certain heating, air-conditioning, and refrigeration applications that require a HACR-rated breaker.
