QOB325 - 25 Amp Circuit Breaker

QOB325 - 25 Amp Circuit Breaker

The QOB325 is a 25-amp, 3-pole bolt-on circuit breaker used to protect your three-phase electrical circuits from overloads and short circuits. Built for use in compatible Type QOB panelboards, its bolt-on mounting helps you to keep the breaker firmly secured to the panel, making it a popular choice in commercial and industrial electrical systems. Rated 10kA at 240VAC, the QOB325 is commonly installed in distribution panels serving lighting, HVAC equipment, machinery, and other branch circuits. Its compact size makes it a practical replacement when an existing breaker needs to be swapped out or when adding circuits to compatible equipment. For electricians and maintenance teams, it's simply a reliable breaker that gets the job done without unnecessary complexity.
