BQ220240 - Quadplex 20/40 Circuit Breaker

BQ220240 - Quadplex 20/40 Circuit Breaker

The Eaton BQ220240 Type BQ Quadplex Circuit Breaker combines one 20-amp two-pole breaker and one 40-amp two-pole breaker in a single compact unit for you to use in Eaton Type BR loadcenters. Its quadplex design allows two separate 240-volt circuits to be installed while using only one breaker space, making it a common choice when additional circuits are needed and available panel space is limited.

This breaker is frequently used during panel upgrades, renovations, and equipment additions where a mix of 20-amp and 40-amp two-pole protection is required. Typical applications include air conditioning systems, heat pumps, electric water heaters, electric heating equipment, workshop machinery, and dedicated appliance circuits.

The BQ220240 uses a thermal magnetic trip mechanism to provide overload and short-circuit protection and installs in compatible loadcenters using a plug-on connection. A built-in rejection tab helps you ensure proper placement within approved panels. With a 10 kAIC interrupting rating, UL 489 listing, HACR classification, and compatibility with both copper and aluminum conductors, it is suitable for a wide range of residential and light commercial electrical systems.
