Square D QOT220 Tandem Plug On Circuit Breaker

Square D QOT220 Tandem Plug-On Circuit Breaker is a two-pole, 20-amp tandem device that fits in the space of a single breaker in compatible Square D QO load centers, providing two circuits in one slot. It is a plug-on breaker rated for 120/240 VAC with an interrupting rating of 10 kA, and it belongs to the QOT family of tandem breakers—CTL devices that are not compatible with plug-on neutral systems. Because QOT tandems are CTL products, installation is restricted to panel positions approved by the panel labeling and only in load centers that explicitly accept QOT tandem breakers. This model is designed for use in panels that support tandem CTL devices and must be installed in designated positions to ensure safe, code-compliant protection.
