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 main 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.
Features
- Designed specifically as a primary main breaker, this 40A, 2-pole device provides essential overcurrent protection for smaller residential services or dedicated outbuilding subpanels. It handles a standard 120/240VAC electrical load, allowing electrical contractors and experienced DIYers to isolate sub-circuits safely without compromising the main system's integrity.
- Engineered on the standard QOM1 frame size, this main breaker seamlessly integrates into convertible QO and Homeline load centers, as well as select metering devices. This exact mechanical pairing eliminates the frustration of unexpected component mismatch delays during a critical panel upgrade or replacement job.
- This unit includes Square D’s signature Visi-Trip indicator, an instant visual alert system that displays a high-visibility window when the breaker trips. This feature takes the guesswork out of troubleshooting, letting you immediately diagnose system faults, restore power faster, and reduce expensive downtime.
- With a robust 10 kAIC (kiloampere interrupting capacity) short-circuit current rating, this thermal-magnetic breaker safely clears high-current electrical faults before they can damage your property or downstream wiring. Fully UL Listed and CSA Certified to meet strict Canadian electrical standards, it delivers absolute peace of mind regarding code compliance and fire prevention.
- Equipped with versatile, factory-installed box lugs, the terminal connections easily accept both aluminum and copper conductors ranging from 12 AWG up to 2/0 AWG. This flexible mechanical range accommodates thick feeder cables effortlessly, simplifying wire pulling and ensuring a code-compliant, low-resistance termination every time.
