Siemens Q315 Three Phase Plug In Circuit Breaker

Siemens Q315 is a three-pole, 15-amp plug-in circuit breaker in the Type QP family, delivering 240 V AC protection for three-phase circuits. It uses a plug-in mounting that fits standard 1-inch-per-pole modules in compatible Siemens load centers and meter combos, allowing quick, bolt-free replacement. This standard-trip device (no AFCI/GFCI function) carries a 10,000 AIC interrupt rating at 240 V, and its 3-pole form factor occupies three module widths in the panel. The Q315 is designed for three-phase distribution within Siemens panel ecosystems, providing thermal-magnetic trip action to promptly interrupt fault currents and protect wiring and equipment. As a genuine Siemens QP component, it integrates with other QP breakers in Siemens/Murray/ITE-compatible installations.
