Eaton / Cutler-Hammer BQ220250 20/50A Quadplex Miniature Circuit Breaker

This quadplex breaker is designed for Eaton, Cutler-Hammer, Bryant, and Westinghouse Type BR load centers that accept CTL (Circuit Total Limiting) tandem or quadplex breakers. The panel bus bar must have notched stabs to accept the rejection tab on this breaker.

The BQ series features an independent trip mechanism. This means the outer 20A two-pole circuit and the inner 50A two-pole circuit operate independently. If one circuit experiences an overload or short circuit, it will trip without disconnecting the other circuit.

The BQ220250 features an independent trip mechanism, meaning the outer and inner circuits trip separately. The BQC220250 features a common trip mechanism, where a fault on either the inner or outer poles will trip all circuits synchronously.

This quadplex breaker provides two separate 240V circuits (one 20A and one 50A) while only occupying two standard 1-inch spaces in the load center. This helps maximize capacity in crowded panels.

The BQ220250 is a CTL (Circuit Total Limiting) breaker. It includes a physical rejection tab on the bus connection side to prevent installation in panel positions that are not rated for tandem or quadplex breakers.

Yes, Eaton BQ quadplex circuit breakers carry a listing for HACR (Heating, Air Conditioning, and Refrigeration) applications, making them suitable for protecting heat pumps, air conditioners, and similar equipment.
