Eaton / Cutler-Hammer BQ215240 15/40A Quadplex Miniature Circuit Breaker

The BQ215240 provides four poles of protection, featuring two 15A outer poles and two 40A inner (center) poles.

The BQ215240 features independent trip technology on both the 15A and 40A circuits. If your application requires a common trip mechanism for 240V loads, you will need the BQC series equivalent, catalog number BQC215240.

As a quadplex breaker, it provides four poles of overcurrent protection while occupying only two standard 1-inch panel spaces in your load center.

Yes, the BQ215240 is a Class CTL (Circuit Total Limiting) breaker equipped with a rejection tab. It is designed specifically for CTL-rated load centers and will not seat properly in older non-CTL panels.

Yes, Eaton Type BQ quadplex circuit breakers carry a listing for HACR (Heating, Air Conditioning, and Refrigeration) applications.

Yes, the 15A outer poles on the BQ215240 are switch-duty (SWD) rated, meaning they are approved for the regular switching of 120V fluorescent lighting circuits.

No. The BQ215240 is a Type BR breaker designed exclusively for Eaton BR, Westinghouse, Bryant, and Challenger load centers. It is not interchangeable with Square D, Siemens, or GE panels, even if they appear to have similar plug-on designs.

Yes, if you need to manually disconnect both 15A outer poles simultaneously, you can use an Eaton THOW handle tie. Note that a handle tie provides manual switching convenience but does not convert the independent trip breaker into a common trip breaker.
