BQ240250 - Quadplex 40/50 Circuit Breaker

BQ240250 - Quadplex 40/50 Circuit Breaker

The Eaton BQ240250 Type BQ Quadplex Circuit Breaker packs a 40-amp two-pole breaker and a 50-amp two-pole breaker into a single assembly for Eaton Type BR loadcenters. Its design allows two 240-volt circuits to fit in a single breaker space, making it useful for your panel upgrades, equipment additions, and remodeling projects where multiple circuit sizes are needed.

This breaker is used to supply HVAC systems, heat pumps, water heaters, compressors, pumps, welders, and other 240-volt equipment. The combination of 40A and 50A circuits lets a single assembly handle multiple loads without taking up extra space.

It installs with a plug-on connection, and the integrated rejection tab ensures proper placement in compatible panels. With thermal magnetic trip protection, a 10 kAIC interrupting rating, UL 489 certification, HACR classification, and compatibility with copper and aluminum conductors, the BQ240250 is reliable for your residential and light commercial electrical systems.
