Square D QOB260 Industrial Grade Circuit Breaker

Square D QOB260 is a 60 A, two‑pole miniature circuit breaker designed for 120/240 V AC service and bolt‑on mounting in compatible Square D enclosures. It belongs to Schneider Electric’s QO/QOB family, delivering thermal‑magnetic trip protection with a 10 kA interrupt rating and featuring Visi‑Trip visual trip indication to show when the breaker has opened. The compact form factor measures roughly 2.91 in long, 1.50 in wide, and 3.12 in high, making it suitable for standard distribution panels in residential, commercial, and light‑industrial applications. This model is a standard QOB260 (60 A, 2‑pole) with the same basic ratings, and variants exist such as QOB260EPD, which adds 30 mA ground‑fault protection while preserving 120/240 V operation and 10 kA interrupt capacity. In practice, the QOB260 provides reliable overcurrent protection for branch circuits in panels that require bolt‑on protection within the Square D QO/QOB line.
