Eaton / Cutler-Hammer BQC2302120 30/20A Quadplex Miniature Circuit Breaker

The BQC2302120 is a CTL (Circuit Total Limitation) breaker. It features a physical rejection tab on the bus connection side and is designed exclusively for use in Eaton Type BR load centers with notched bus stabs.

No. Because the BQC2302120 includes a CTL rejection tab, it cannot be installed in older non-CTL panels that lack notched bus stabs. For non-CTL applications, a replacement breaker without a rejection clip is required.

This quadplex breaker provides one 2-pole 30A circuit for 240V loads and two independent 1-pole 20A circuits for 120V loads. This configuration allows you to add multiple circuits while only occupying two standard 1-inch panel spaces.

Yes, the BQC series features a common trip mechanism for the 2-pole 30A circuit, ensuring both legs trip simultaneously during an overcurrent event. The two 1-pole 20A circuits operate and trip independently of the 30A circuit and each other.

Despite providing four separate poles, this quadplex breaker requires only two standard 1-inch spaces in a compatible Eaton Type BR load center.

The BQ2302120 features independent trip mechanisms for all poles, meaning the 2-pole circuit does not trip synchronously. The BQC2302120 features a common trip mechanism for the 2-pole 30A circuit, which is required by code for most modern 240V loads.

Yes, all Eaton Type BQC quadplex circuit breakers carry a listing for HACR applications, making this breaker suitable for protecting heating, air conditioning, and refrigeration motor loads.
