<br><strong>What are QO Breakers and where are they used?</strong><br> <br>QO (plug-on) and QOB (bolt-on) <strong>one-, two- and three-pole</strong> thermal-magnetic circuit breakers provide overcurrent protection and switching on <strong>ac and dc systems.</strong> <strong>Plug-on QO</strong> circuit breakers are for use in QO load centers, NQ and NQOD panelboards, OEM mounting bases, and Speed-D switchboard distribution panels. <strong>Plug-on QO</strong> circuit breakers are for use in QO load centers, NQ and NQOD panelboards, OEM mounting bases, and Speed-D switchboard distribution panels. <br><br><strong>What are the general characteristics of QO Breakers?</strong><br> <br>QO and QOB circuit breakers have <strong>Visi-Trip trip indication</strong>, which provides a visual indication that the circuit breaker has <strong>tripped and interrupted </strong> the circuit. They feature an <strong>over center, trip-free toggle mechanism with quick-make, quick break action</strong> and positive handle indication. The<strong> tripping mechanisms</strong> in two- and three-pole circuit breakers operate such that an overcurrent on any pole of the circuit breaker will cause all poles of the circuit breaker to <strong>open simultaneously.</strong> <br><br><strong> What are the specific characteristics and benefits of this breaker?</strong> <br><br> <strong>QO-EPD/EPE circuit breakers</strong> provide <strong>overload and short circuit</strong> protection combined with <strong>Class B ground fault protection</strong> They are designed to provide ground fault protection of equipment at a <strong>30 mA level (EPD) or 100 mA level (EPE)</strong> They are not designed to protect people from electrical shock <br><br>This is a <strong>3‑pole</strong> <strong>QO</strong> circuit breaker rated <strong>50A</strong>, <strong>208Y/120Vac</strong>, <strong>10kA</strong> This has <strong>6mA Class A ground‑fault protection</strong> and a <strong>pigtail neutral</strong>
