Schneider Electric QOB220EP0 is a two‑pole, 20‑amp miniature circuit breaker in the Square D QO/QOB bolt‑on family. It is rated for 120/240 VAC service and offers a 10 kA interrupt rating, making it suitable for use in standard residential and light‑commercial panelboards. The bolt‑on form factor enables secure mounting in compatible QO/QOB panels, providing simultaneous disconnection of both hot legs for multiwire circuit protection. This model protects branch circuits such as lighting, outlets, and small‑appliance circuits by interrupting current when overload conditions occur.
