BQ230240 - Quadplex 30/40 Circuit Breaker

BQ230240 - Quadplex 30/40 Circuit Breaker

The Eaton BQ230240 Type BQ Quadplex Thermal Magnetic Circuit Breaker is designed to provide two independent 240-volt branch circuits within a single compact breaker assembly. Featuring one 30-amp two-pole breaker and one 40-amp two-pole breaker, this quadplex configuration helps you maximize available space in compatible Eaton Type BR loadcenters while accommodating multiple dedicated circuits. It is a practical choice for your panel upgrades, electrical renovations, equipment additions, and other projects where adding new circuits without expanding the panel is desirable.

Built with Eaton's proven thermal magnetic trip technology, the BQ230240 helps protect your conductors and connected equipment from overloads and short circuits. The breaker installs using a plug-on connection and includes Eaton's rejection tab feature for proper placement in approved loadcenters. Rated for 120/240 VAC operation with a 10 kAIC interrupting capacity, the BQ230240 is commonly used to supply power to larger residential and light commercial loads such as air conditioning systems, heat pumps, water heaters, air compressors, pumps, workshop equipment, and other dedicated 240-volt applications. Its combination of a 30-amp and 40-amp two-pole breaker makes it especially useful when different load requirements must be accommodated within limited panel space.
