Schneider Electric QOB360 Three-Phase Circuit Breaker

Schneider Electric's Square D QOB360 is a three-pole bolt-on molded‑case circuit breaker rated for 60 A at 240 V (120/240 VAC, 3‑phase). It is designed for bolt‑on mounting in compatible QOB enclosures and provides thermal‑magnetic overcurrent protection with a 10 kA interrupt rating at 240 V. The device accepts conductors sized from 8 AWG up to 2 AWG, enabling connection to common branch circuits in commercial and light‑industrial panels. As part of the QOB family, the QOB360 is intended for three‑phase distribution on 120/240 V systems, protecting circuits that feed motors, pumps, conveyors, fans, and other equipment up to 60 A. This bolt‑on breaker is compatible with Square D load centers and distribution panels that specify QOB hardware for three‑phase protection, helping simplify replacement and upgrade in existing installations. With its precise 60 A rating and 10 kA short‑circuit capacity at 240 V, the QOB360 provides a clear, reliable protection point for downstream devices while aligning with standard wiring practices in commercial electrical gear.
