Eaton / Cutler-Hammer BQC240230 30/40A Quadplex Miniature Circuit Breaker

This quadplex breaker requires two full one-inch spaces in a compatible Eaton Type BR load center. It provides two independent 2-pole circuits while only taking up the space of a standard 2-pole breaker.

It is designed exclusively for Eaton Type BR load centers that are notched to accept Class CTL tandem or quad breakers. It features a rejection tab that prevents installation in panel slots not rated for multiplex breakers.

The outer two poles form the 40A double-pole circuit, while the center two poles form the 30A double-pole circuit. Both the 30A and 40A circuits feature independent common trip mechanisms.

Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 30A or 40A 240V circuit.

Yes, the BQC series features an internal common trip. If a fault occurs on either leg of the 30A or 40A circuit, both poles of that specific circuit will trip simultaneously to safely disconnect the multi-wire branch circuit.

The terminals accept 14 AWG to 4 AWG copper or aluminum wiring. Always verify the correct wire gauge based on the specific 30A and 40A circuit requirements and local electrical codes.

Yes. Eaton acquired Cutler-Hammer, and the current Eaton Type BR series is the direct, UL-listed replacement for legacy Cutler-Hammer and Bryant Type BR load centers.

This is a Class CTL breaker equipped with a rejection tab. If it does not seat fully, you may be trying to install it in a panel space that is not notched to accept tandem or quad breakers. Never force or modify the breaker to fit.

The LI designation indicates that the breaker provides both long-time and instantaneous trip functions. The long-time function protects against sustained mild overloads, while the instantaneous function reacts immediately to severe short circuits.
