QBHW2080 - 80Amp Circuit Breaker

QBHW2080 - 80Amp Circuit Breaker

If you're looking for a QBHW2080 circuit breaker, getting the details right matters. This is an 80-amp, 2-pole Quicklag QBHW breaker with a bolt-on connection and thermal-magnetic protection. It's rated for 120/240VAC and has a 22kA interrupting rating, giving you the key specifications needed when matching a breaker to compatible electrical equipment. The thermal-magnetic trip design handles two different problems: the thermal element responds to prolonged overloads, while the magnetic element reacts to short-circuit conditions. The QBHW2080 is also HACR rated and carries a 40°C rating. Its bolt-on design provides a secure connection in equipment designed for QBHW breakers. Replacing an existing breaker? Don't go by appearance alone. Check the QBHW2080 part number along with the amperage, poles, voltage, AIC rating, and mounting style to make sure everything matches your application.

Material Compliance and Certifications

• The QBHW2080 is identified as a 40°C, HACR-rated Quicklag thermal-magnetic circuit breaker. Material-compliance requirements and certifications can depend on the particular application and equipment involved, so any required approvals should be checked against current product documentation before the breaker is installed. This is especially important when a project, facility, or local electrical code calls for specific certifications.

Where It Works Best

• The QBHW2080 makes sense when the job calls for an 80 amp, 2-pole QBHW bolt-on circuit breaker with a 120/240VAC rating and 22kA interrupting capacity. That can include compatible commercial and industrial electrical distribution equipment, as well as appropriate HVAC-related applications where an HACR-rated breaker is specified.
