Q2150B - 150A Circuit Breaker

Q2150B - 150A Circuit Breaker

The Q2150B is a 150-amp, 2-pole Type QPP plug-in circuit breaker rated for 120/240VAC. It has a 10k A.I.C. rating at 120/240VAC and is rated at 40°C. If you're replacing an existing breaker, there are a few details you'll want to check before installation. This model measures 5.25" high x 4.0" wide x 2.56" deep and requires 4–6 spaces, so both the electrical ratings and the available panel space matter. The plug-in design is intended for compatible equipment that accepts this breaker type. For maintenance and replacement work, the Q2150B is a practical option when the existing application calls for the same 150A rating, two-pole configuration, voltage, breaker type, and interrupting capacity. Always compare the specifications with your existing equipment rather than choosing a breaker based on amperage alone.
