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 40A 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
- Integrated with the patented Visi-Trip system, a high-visibility red mechanical indicator snaps into view the moment the breaker trips due to a fault. This allows maintenance staff and facility managers to instantly identify the source of power loss in a crowded, multi-row panelboard, drastically reducing diagnostic time and speeding up the restoration of critical services.
- Providing 10kA of interrupting capacity at 120/240V AC, this common-trip 40A breaker is the standard for powering mid-sized loads such as commercial water heaters, small HVAC air handlers, and commercial kitchen machinery. The simultaneous opening of both poles ensures that if one leg of the circuit faults, the entire power supply is disconnected, preventing dangerous back-feeding and protecting your three-phase or split-phase equipment from damage.
- As part of the world-class QO family, the QOB240 is built with a proprietary pressure-plate wire terminal and a quick-make, quick-break mechanism that extends the life of the internal contacts. Choosing an authentic Schneider Electric component ensures full UL Listing and CSA certification, guaranteeing that your electrical infrastructure remains code-compliant and your property insurance requirements are fully satisfied.
