Schneider Electric Square D 2-Pole 20A QO Circuit Breaker – Model QO220
The Schneider Electric Square D QO220 is a 2-pole, 20-amp thermal magnetic circuit breaker built for reliable overcurrent protection in residential and light commercial electrical systems. A go-to choice for licensed electricians and experienced DIYers alike, the QO220 is engineered for fast plug-on installation into Square D QO load centers — making it ideal for service upgrades, panel additions, kitchen and bathroom circuit work, and any application requiring a dependable double-pole breaker. With its industry-trusted QO platform and CSA/UL dual certification, this breaker is inspection-ready right out of the box.
Key Features
| Thermal Magnetic Trip Mechanism | Provides dual-mode protection — thermal sensing for sustained overloads and magnetic sensing for instantaneous short-circuit response — keeping circuits and equipment safe under real job site conditions. |
| VisiTrip™ Indication | A distinctive visual indicator clearly shows when the breaker has tripped, allowing electricians and homeowners to identify a faulted circuit at a glance without guesswork or a multimeter. |
| Quick-Make, Quick-Break Action | The over-center, trip-free toggle mechanism ensures fast, decisive switching action and positive handle indication — critical for safe operation during panel work and load testing. |
| Plug-On Mounting | Snaps directly into Square D QO load centers with no tools required for mounting — speeding up installation on multi-circuit panel builds and reducing time in the box. |
| Plug-On Neutral Compatible | Compatible with Square D's plug-on neutral system, enabling cleaner wiring and faster AFCI/GFCI upgrades without running a separate neutral pigtail to the breaker. |
| Factory Accessory Ready | Supports a full range of factory-installed accessories including auxiliary switches, alarm switches, and shunt trips — useful for commercial applications requiring remote monitoring or automated shutoff. |
| Compact 3/4" Width Design | The slim QO profile maximizes circuit density in the panel, giving contractors more flexibility when working with tight enclosures or high-circuit-count load centers. |
