Description
QO and QOB one, two and three pole thermal magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems. These circuit breakers have an over center, trip free toggle mechanism with quick make, quick break action and positive handle indication. They also have VisiTrip trip indication, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit. This 3 pole QO circuit breaker is rated at 30A at 120/240VAC. This unit provides 10kA breaking capacity and plug in mounting. A full line of features and factory installed accessories are also available such as shunt trips, auxiliary switches and alarm switches. QO circuit breakers are UL Listed under UL File E84967 and are CSA Certified under CSA Master Contract 153555. QO circuit breakers are UL Listed under UL File E84967 and are CSA Certified under CSA Master Contract 153555
Features
- The Schneider Electric (Square D) QO330 is a 30-Amp, 3-pole miniature circuit breaker featuring the industry-standard QO plug-on mounting system. It is designed for instant installation into Square D QO load centers and NQ panelboards. The "dual-shield" design ensures a secure, vibration-resistant connection to the bus bar without the need for mounting screws or specialized tools.
- As a 3-pole breaker, the QO330 provides simultaneous overcurrent protection for 240V AC three-phase loads. With its 30-Amp rating, it is the common choice for protecting mid-sized HVAC compressors, commercial water heaters, and small industrial machine tools where reliable, triple-pole disconnection is required.
- Equipped with the patented Visi-Trip™ red indicator, this breaker takes the guesswork out of troubleshooting. When the breaker trips due to a fault, a highly visible red flag appears in the window of the unit. This allows maintenance staff in Canadian commercial or industrial facilities to identify the problem circuit at a glance, significantly reducing downtime.
- The QO series is famous for its Quick-Open mechanism, which snaps the contacts open faster than standard breakers. This rapid response limits the "let-through" energy during a short circuit, protecting your downstream wiring and expensive three-phase equipment from the mechanical and thermal stresses of an electrical surge.
- Despite providing full three-phase protection, the QO330 occupies only 2.25 inches of space (three standard 3/4-inch QO slots). This high-density design allows you to maximize the number of circuits in your panelboard, making it an efficient choice for both new installations and system retrofits.
