The Square D QOU210U is a two-pole molded‑case circuit breaker from Square D (Schneider Electric) engineered to provide reliable overcurrent protection for 240 V AC circuits. As part of the QOU series, this bolt‑on, thermal‑magnetic device carries a 10 A nominal rating, 240 V operating voltage, and a 10 kA short‑circuit interrupting capacity at 240 V, making it suitable for protecting small branch circuits in Square D installations. With two poles in a compact molded‑case form factor, the QOU210U is designed for bolt‑on mounting in Square D panels where space and secure mounting are priorities.
