Eaton / Cutler-Hammer BQC230250 30/50A Quadplex Miniature Circuit Breaker

This breaker is designed for Eaton Type BR load centers. Because it is a CTL (Circuit Total Limitation) breaker, your panel must support quad breakers and have notched bus stabs to accept the rejection tab on this unit.

Yes. Eaton manufactures the BR line as a direct, UL listed replacement for legacy Bryant, Westinghouse, and Challenger Type BR breakers. As long as your older panel accepts CTL quad breakers, the BQC230250 is a compliant replacement.

This quadplex breaker requires two standard 1-inch spaces in your load center. It provides four poles of protection, creating two separate 240V circuits in a compact 2-inch footprint, which is ideal for adding capacity to a full panel.

The BQC230250 provides two separate 240V circuits. The outer two poles form the 30A 2-pole circuit, and the inner two poles form the 50A 2-pole circuit. Both circuits feature a common trip design.

The BQC series features a common trip mechanism for both the 30A and 50A circuits. If an overload or short circuit occurs on one leg of either 240V circuit, both poles for that specific circuit will trip simultaneously, ensuring safe disconnection of connected 240V loads.

The rejection tab is a CTL (Circuit Total Limitation) safety feature. It prevents the breaker from being installed in panel slots that are not designed to handle tandem or quad breakers. You must install this breaker in a slot with a notched bus bar.

Yes, this breaker is HACR (Heating, Air Conditioning, and Refrigeration) rated. This makes it suitable for protecting dedicated 240V HVAC loads like heat pumps, air compressors, and air conditioning units.
