Square D by Schneider Electric Q210 Circuit Breaker

Square D by Schneider Electric QO210 is a 10-amp, two-pole miniature circuit breaker designed for residential and light commercial distribution. This plug-on unit protects 120/240 VAC circuits (1-phase, 2-wire service) with a thermal-magnetic trip and carries a 10 kA interrupt rating, enabling fault currents to be interrupted quickly and safely up to 10,000 A. As part of the QO family, the QO210 is intended for use in Square D QO load centers and panelboards, OEM mounting bases, and other distribution configurations that accept QO plug-in breakers, offering straightforward replacement in compatible enclosures. The two-pole design ensures simultaneous disconnection of both conductors for multi-wire branch circuits, aligning with common electrical code requirements for reliable protection in standard service setups.
