Square D QOB115EPD Molded Case Circuit Breaker

Square D QOB115EPD is a bolt‑on, 1‑pole molded‑case circuit breaker rated for 120 VAC and 15 A, designed for use in Square D QOB panelboards and distribution enclosures. It delivers a 10,000 A interrupting capacity at 120 V, providing robust protection for branch circuits in residential or light commercial applications. The device employs a thermal‑magnetic trip mechanism with both long‑time and instantaneous protection, helping prevent overloads and short circuits from escalating into faults. As part of the QOB family, it serves as the bolt‑on counterpart to the QO line, offering secure, flush mounting in compatible panels where plug‑in breakers aren’t suitable. Typical uses include safeguarding lighting circuits, general receptacle runs, and other individual branches fed from a QOB installation, making it a standard, field‑reliable component in Square D electrical systems (Schneider Electric).
