Q2L3150 - 150 Amp Circuit Breaker

Q2L3150 - 150 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the small details matter just as much as the amp rating. The Q2L3150 is a 150A, 3-pole thermal-magnetic circuit breaker designed for compatible Q2L applications. It carries a 10k AIC rating at 240VAC and uses a non-interchangeable trip unit. One detail worth checking closely is the connection style: this breaker has lug terminals on both the line and load sides. Physically, the Q2L3150 measures approximately 6.5 inches high, 4.5 inches wide, and 3.13 inches deep. If you're maintaining older electrical equipment and need to match an existing breaker, compare these dimensions, ratings, and connection details with the breaker being replaced. The goal is a proper form, fit, and functional match—not simply finding another 150 amp breaker. When correctly matched to the intended equipment and used within its ratings, the Q2L3150 is built to last and can help keep compatible legacy equipment in service.

Material Compliance and Certifications

• Specific certification and material-compliance information is not provided in the available specifications for the Q2L3150. If your application requires a particular listing or compliance standard, check the markings on the individual breaker and the applicable equipment documentation before installation. UL, CSA, RoHS, or other certifications should not be assumed without supporting product information.

Where It Works Best

• The Q2L3150 makes the most sense when you're working with existing electrical distribution equipment that requires this specific Q2L breaker configuration. It is particularly relevant for repair and maintenance work where changing the equipment isn't the objective—you simply need a breaker that matches the required electrical and physical characteristics.
