Schneider Electric SE QOU1151200 Circuit Breaker

Schneider Electric's QOU1151200 is a 1-pole miniature circuit breaker rated for 15 A on 120/240 VAC circuits, with a 10 kA short‑circuit interruption capacity. Part of the Square D QOU family, this compact MCB protects a single branch circuit in electrical panels by interrupting current during overloads or faults and then resetting after the fault is cleared. Key specifications include 1-pole, 15 A, 120/240 VAC operation, and a 10 kA interrupting rating, making it suitable for standard residential and light commercial panel installations where reliable, fast fault protection is required. The device is designed for compatibility with Schneider Electric panel enclosures that accept QOU mini breakers and supports straightforward replacement in existing QOU-based installations. In single-pole configurations, the breaker interrupts only the hot conductor, leaving the neutral path intact, which aligns with typical residential wiring practices for branch circuits and helps minimize disruption when servicing individual circuits.
