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 1 pole QO circuit breaker is rated at 20A 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.

Features
- The QO120 is a premium single-pole, 20-Amp Miniature Circuit Breaker designed for Square D QO load centers. It provides essential protection against overloads and short circuits for 120V branch circuits. It is the gold standard for residential and commercial circuits requiring 20-Amp capacity, such as those powering kitchen receptacles, bathroom outlets, and dedicated laundry lines.
- Exclusive to the Square D QO range, the QO120 features the patented Visi-Trip red indicator window. When the breaker trips, a highly visible red flag appears in the window, allowing you to identify the faulted circuit at a glance without having to guess which handle has moved, even in low-light electrical rooms.
- This breaker is engineered exclusively for use in Square D QO load centers, NQ/NQOD panelboards, and switchboards. It utilizes a 3/4-inch space-saving "Plug-On" design. Please note: This will not fit Square D Homeline, Eaton, or Siemens panels; it is strictly compatible with the QO "Blue Label" ecosystem.
- Designed with a "Quick-Make, Quick-Break" internal mechanism, the QO120 reduces internal arcing and contact wear, extending the life of the breaker. It is SWD (Switch Duty) rated for frequent switching of fluorescent and LED lighting, and HACR rated for use with heating, air conditioning, and refrigeration equipment.
- The Square D QO120 is UL Listed and CSA Certified, offering a 10,000 AIR (Amperes Interrupting Rating). Its pressure plate terminals provide a secure, gas-tight connection for both copper and aluminum conductors (#14 to #8 AWG), ensuring long-term reliability and compliance for both residential and industrial installations.
