QOU315 - 15 Amp Circuit Breaker

QOU315 - 15 Amp Circuit Breaker

Some electrical installations call for a breaker that doesn't need a traditional load center. The Square D QOU315 15 Amp 3-Pole Circuit Breaker is designed for those setups, offering overcurrent protection in a compact, unit-mounted design.

The QOU315 also makes troubleshooting a little easier. Its built-in VisiTrip indicator shows when the breaker has tripped, helping you identify the affected circuit without unnecessary guesswork. When space or equipment layout matters, the option to use DIN rail, surface, or flush mounting, with the appropriate accessories, gives you more flexibility during installation.

Key Features and Benefits
