Overview
The Eaton BQ2402115 is a Type BQ CTL quadplex plug-on circuit breaker engineered for single-phase residential and light commercial panelboards. This compact breaker combines two 15-ampere single-pole circuits and one 40-ampere two-pole circuit into a standard two-pole footprint, maximizing load center capacity without sacrificing protection. With 10 kAIC (kiloampere) interrupting rating and thermal-magnetic trip, the BQ2402115 delivers dependable protection across 120/240 VAC systems.
