Square D LL-7380 Three Pole Molded Case Circuit Breaker

Square D LL-7380 is a three-pole molded‑case circuit breaker designated Type QOB, offering a 15‑amp rating and carrying the C65 designation in its model code. As part of the Square D QOB family, this breaker is intended for overcurrent protection of three‑phase branch circuits in compatible panel boards and OEM assemblies. Its three‑pole configuration ensures simultaneous interruption of all conductors in a 3‑phase circuit, helping safeguard motors and other equipment from short circuits or overloads in commercial and light industrial settings. This bolt‑on style device integrates with Square D’s line of QOB breakers and meets the standard form factor used in compatible enclosures, providing reliable protection within the limits of its 15A rating. When selecting a replacement, verify that the panel or base accepts QOB breakers and that a 15A rating aligns with the circuit being protected to maintain proper trip characteristics and code compliance.
