Eaton / Cutler-Hammer BQ230250 30/50A Quadplex Miniature Circuit Breaker

No. The BQ230250 is a CTL (Circuit Total Limiting) breaker equipped with a rejection tab on the bus connection side. It is only compatible with CTL-rated Type BR load centers that feature notched bus stabs designed to accept tandem or quadplex breakers.

This quadplex breaker condenses four poles of protection into just two standard 1-inch panel spaces. This makes it an ideal solution for adding a 30A and a 50A circuit to a crowded Type BR load center without requiring a subpanel.

The BQ series features an independent trip design, meaning the outer and inner circuits trip independently of one another. In contrast, BQC series breakers feature a common trip mechanism where the center or outer poles trip synchronously.

Yes, Eaton BQ quadplex circuit breakers carry an HACR listing. This certifies them for use with heating, air conditioning, and refrigeration equipment that requires reliable thermal-magnetic circuit protection.

Yes. Eaton Type BR breakers are the direct, UL-listed replacements for legacy Bryant, Westinghouse, and Challenger Type BR load centers. You must verify that the specific legacy panel is CTL-rated and accepts quadplex breakers before installation.

The box lugs on this breaker accept copper or aluminum conductors ranging from 14 AWG to 4 AWG. This wide range accommodates the different wire gauges typically required for the separate 30A and 50A circuits.
