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 bolt on 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 QOB330 is a "Bolt-On" version of the legendary Square D QO circuit breaker. Unlike standard plug-on breakers used in homes, this unit features a mounting screw that physically secures it to the bus bar of a Square D NQ or NQOD panelboard. This bolt-on connection is the industry standard for Canadian commercial and industrial facilities because it resists loosening due to vibration or heavy thermal cycling.
- This is a 3-Pole, 30-Amp breaker, designed to provide simultaneous overcurrent protection for all three phases of a 3-phase electrical system. In Canada, it is most commonly used to protect: 3-Phase Motors (up to approx. 7.5 HP at 208V) , Commercial HVAC Units and Exhaust Fans , Industrial Kitchen Equipment (ovens, fryers) , Small Machine Tools in workshops or manufacturing plants.
- The QOB330 is rated for 240V AC. It is the go-to choice for 3-phase branch circuits in 208Y/120V systems, which are the most prevalent power configurations for Canadian office buildings, retail spaces, and light industrial units.
- Equipped with the patented Visi-Trip™ indicator, this breaker makes troubleshooting simple. When the breaker trips, a highly visible red flag snaps into the window on the face of the breaker. This allows maintenance staff to immediately identify which 3-phase circuit has faulted among dozens of others in a dark electrical room.
- The internal contacts are designed to snap open or closed at high speed, regardless of how fast the handle is moved. This "Quick-Make/Quick-Break" action reduces internal arcing, which preserves the life of the contacts and ensures the breaker can reliably interrupt its full rated current over many years of service.
