Siemens Q260 Two-Pole Plug-In Circuit Breaker

Siemens Q260 is a two-pole, 60-amp plug-in circuit breaker designed for 120/240-volt residential electrical systems, compatible with Siemens QP/MP load centers and engineered to drop into standard plug-in slots without bolt-on mounting. It provides thermal-magnetic trip protection in a common-trip 2-pole configuration, with an interrupt rating of 10,000 AIC at 240V, enabling rapid fault clearing while maintaining predictable coordination with adjacent breakers in the same panel. The Q260's plug-in design and 2-pole frame accommodate copper or aluminum conductors in sizes from 8 AWG up to 2/0 AWG, offering flexible wiring for typical residential branch circuits and feeder applications. As part of Siemens' Q-Line, this model is specified as a 2-pole, 60A device that fits in compatible QP/MP panels and supports common-trip operation to ensure both hot legs disconnect together when the breaker trips. Typical applications include protecting branch circuits in home service panels, subpanels, garages, and workshops, where a reliable 60-amp feeder or multi-wire branch circuit requires coordinated protection and easy plug-in installation.
