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 2 pole QO circuit breaker is rated at 150A 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
- Rated for a massive 150 Amps at 120/240V AC, this 2-pole miniature circuit breaker provides robust infrastructure power distribution. For residential and commercial electrical contractors, this ensures the continuous, high-threshold ampacity required to feed large outbuilding sub-panels, heavy-duty industrial machinery, or multi-unit HVAC compressor banks without facing thermal nuisance trips.
- Engineered with Square D's exclusive Visi-Trip visual indicator, this breaker instantly displays a highly visible, bright red indicator flag within the window the moment it moves to the tripped state. This allows property managers and service technicians to immediately identify the faulted line out of a dense column of switches, completely eliminating diagnostic guesswork and slashing system downtime during emergencies.
- This premium circuit breaker features a 2-pole plug-on mounting design that occupies 4 standard panel spaces due to its reinforced, heavy-duty casing. It seats securely onto the busbars of Square D QO load centers, creating a vibration-resistant physical bond that eliminates loose-joint arching, though it is not physically compatible with Homeline or third-party manufacturer interiors.
- Built with large, integrated mechanical box lugs, this assembly accepts heavy-gauge copper or aluminum conductors ranging from 1 AWG up to 300 kcmil. Tightening the lug screws to the exact manufacturer-specified torque of 250 lbf-in (28.3 N-m) ensures optimal, uniform compression that counters conductor cold-flow behavior, eliminating localized resistance hot spots and loose wire conditions over years of service.
- Carrying comprehensive CSA and UL listings alongside an official HACR rating, this miniature circuit breaker is code-certified to handle the intense inductive inrush currents associated with heating, air conditioning, and refrigeration equipment. It operates flawlessly up to an ambient rating of 40°C (104°F), satisfying strict Canadian Electrical Code mandates for streamlined final site inspections.
