Schneider Electric QOB3110VH Mini Circuit Breaker

Schneider Electric's Square D QOB3110VH is a bolt-on, three‑pole molded‑case circuit breaker rated for 110 A with 120/240 VAC operation. It provides a 22 kA interrupting capacity at 240 VAC and uses a thermal‑magnetic trip mechanism for overload and short‑circuit protection. As part of the QOB family, this 3P device is designed for bolt‑on mounting in QOB load centers and panelboards, making it suitable for protecting three‑phase feeders in commercial and light industrial distribution systems. Its 110 A rating and 240 V nominal operating range are intended for three‑phase circuits in environments where reliable disconnection is required, such as distribution panels and machine control panels.
