Description
Part of the Cutler-Hammer BR series by Eaton, the BQ250250 is a quadplex breaker that provides two independent 50A two-pole circuits while occupying just two 1-inch spaces. This space-saving design is ideal for adding high-draw 240V loads to crowded panels. It installs into Eaton BR, Bryant, Westinghouse, and Challenger load centers that accept Class CTL breakers. Rated for 10 kAIC at 120/240VAC, it includes a rejection tab and independent trip mechanisms for reliable protection.Specifications

Product FAQs
7 answersWhat load centers are compatible with the BQ250250 circuit breaker?
This breaker is designed for use in Eaton BR series load centers. It is also backward compatible with legacy Bryant, Westinghouse, and Challenger panels that accept Type BR breakers.
Does the BQ250250 require a specific type of bus bar stab in the panel?
Yes. This is a Class CTL (Circuit Total Limiting) breaker with a rejection tab. It must be installed in a panel space specifically designed to accept tandem or quadplex breakers, which typically features a notched bus bar.
How many panel spaces does the BQ250250 require?
As a quadplex breaker, it provides two separate 2-pole 50A circuits while only occupying two standard 1-inch panel spaces.
Does this breaker feature an internal common trip mechanism?
No, the BQ250250 features independent trip mechanisms for both the center and outer 2-pole circuits. If one leg trips, it will not automatically trip the other leg internally.
Can I use the BQ250250 for 240V appliances if it has independent trip?
Yes, but to comply with NEC requirements for 240V circuits, you must install an approved handle tie (such as the Eaton THOW) to ensure both ungrounded conductors can be manually disconnected simultaneously.
Is this breaker HACR rated?
Yes, like all Eaton Type BQ quadplex circuit breakers, the BQ250250 is HACR rated for use with heating, air conditioning, and refrigeration equipment.
What is the difference between the BQ250250 and BQC250250?
The BQ250250 features independent trip mechanisms for its circuits, while the BQC250250 features internal common trip mechanisms.
