Schneider Electric Square D QOT12020 Circuit Breaker

Schneider Electric's Square D QOT12020 is a 1-pole, 20-amp miniature circuit breaker in the QOT family, designed for 120/240 V electrical systems. It uses a thermal-magnetic trip mechanism to protect a single branch circuit from overloads and short circuits and carries a 10 kA interrupt rating, making it suitable for typical residential and light commercial panels. This model is intended for use in compatible Square D load centers and panelboards that accept QOT-style breakers, providing reliable overcurrent protection for circuits such as lighting, outlets, and small-appliance runs while preserving panel space in tandem-capable installations. As a single-pole device, it protects one hot leg of a 120/240 V circuit and integrates with the broader Square D ecosystem for consistent protection and easy replacement in compatible enclosures.
