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 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 QO215 is a premium 2-pole, 40-Amp Miniature Circuit Breaker designed for Square D QO load centers. It provides simultaneous overcurrent protection for both "hot" legs of a 120/240V circuit. It is a heavy-duty choice commonly used for high-demand residential and commercial appliances, such as electric water heaters, central air conditioning units, and EV chargers.
- A signature feature of the QO240 is the patented Visi-Trip red indicator. When the breaker trips due to a fault or overload, a highly visible red flag snaps into view in the window. This allows you to identify the specific tripped circuit instantly among a sea of black handles, even in dark electrical closets or basements.
- This breaker is engineered exclusively for Square D QO "Blue Label" load centers and NQ panelboards. It uses a 1.5-inch wide (two 3/4-inch spaces) plug-on design. Note: It is not cross-compatible with Square D Homeline, Eaton, Siemens, or GE panels. Always check for the "QO" branding on your panel door before purchasing.
- The QO240 is built with an internal common-trip mechanism. If a short circuit or overload occurs on just one of the poles, both poles trip at exactly the same time. This prevents "single-phasing"—a condition where a motor or heater remains partially energized, which can lead to overheating, equipment failure, or electrical fires.
- The Square D QO240 is UL Listed and CSA Certified with a 10,000 AIR (Amperes Interrupting Rating). It features high-quality pressure plate terminals that ensure a secure, gas-tight connection for copper or aluminum conductors (#8 to #2 AWG). Its "Quick-Make, Quick-Break" mechanism reduces internal arcing, significantly extending the life of the breaker.
