BQ220250 - Quadplex 20/50 Circuit Breaker

Adding new 240-volt circuits can become challenging when an electrical panel is already running out of available space. The Eaton BQ220250 Type BQ Quadplex Circuit Breaker helps make better use of existing panel capacity by combining one 20-amp two-pole breaker and one 50-amp two-pole breaker into a single compact unit. By fitting two independent circuits into a single breaker position, it provides a convenient way to expand circuit capacity without replacing the loadcenter.

This configuration is often used during panel upgrades, equipment replacements, and remodeling projects where different circuit sizes are needed in the same panel. You'll commonly find the BQ220250 serving equipment such as air conditioners, heat pumps, electric water heaters, compressors, workshop machinery, and other dedicated 120/240-volt loads. The combination of 20A and 50A protection allows a variety of equipment to be accommodated while conserving valuable breaker space.
