Eaton / Cutler-Hammer BQC230220 20/30A Quadplex Miniature Circuit Breaker

This breaker is designed for Eaton Type BR load centers that accept CTL (Circuit Total Limitation) breakers. It requires panel positions with notched bus stabs. It is also a UL-listed replacement for older Westinghouse, Challenger, and Bryant panels that use Type BR breakers.

No. The BQC230220 is a CTL breaker equipped with a rejection tab. It will only seat properly in panel positions that feature notched bus stabs designed to accept tandem or quad breakers.

Eaton BQC breakers feature a common trip mechanism for both the inner and outer two-pole circuits. If one leg experiences a fault, both legs of that 240V circuit will trip simultaneously. Standard BQ breakers feature independent trips for the outer poles.

This quadplex breaker provides two separate 240V circuits while occupying only two panel spaces. The outer poles form the 30-amp, 2-pole circuit, and the center poles form the 20-amp, 2-pole circuit.

Yes. Eaton acquired Cutler-Hammer, and the BQC230220 is the direct replacement for older Cutler-Hammer, Westinghouse, and Bryant quad breakers with the same amperage and frame specifications.

The LI designation stands for Long-Time and Instantaneous trip functions. This indicates a standard thermal-magnetic trip unit, where the thermal element protects against gradual overloads (Long-Time) and the magnetic element protects against short circuits (Instantaneous).

The rejection tab is a safety feature specific to CTL (Circuit Total Limitation) breakers. It physically prevents the quad breaker from being installed in panel slots that are not rated for multiple circuits, ensuring the panel does not exceed its maximum designed circuit capacity.
