QB15 - 15 Amp Circuit Breaker

QB15 - 15 Amp Circuit Breaker

The QB15 15-amp single-pole circuit breaker is a solid choice when you need dependable protection in a QB-frame panel without taking up extra space. Rated at 10 kAIC at 120 VAC, it’s built to handle everyday overloads and short circuits before they turn into bigger problems. The bolt-on design keeps the breaker firmly seated, which matters during service work and long-term use. Its narrow profile also helps when the panel is already crowded and there’s no room for larger replacements.

This breaker is commonly used in branch circuits where consistent performance is expected, not optional. It installs cleanly, fits as intended, and does its job quietly in the background—exactly what most electricians and facility managers want.
