Product FAQs
7 answersWhat load centers are compatible with the BQ230230 circuit breaker?
This plug-on quadplex breaker is designed for Eaton Type BR load centers. It is also a UL-approved replacement for legacy Westinghouse, Challenger, and Bryant panels that accept Type BR breakers.
How much panel space does the BQ230230 require?
This quadplex breaker requires two standard 1-inch panel spaces to provide two independent 240V circuits.
Does this breaker have a rejection tab for CTL panels?
Yes, the BQ230230 is a CTL (Circuit Total Limiting) breaker equipped with a rejection tab. It must be installed in panel positions with notched bus stabs designed to accept tandem or quad breakers.
How are the two 30A circuits configured on this quadplex breaker?
The BQ230230 provides two separate 30A, 240V circuits. The two outer poles are linked to form one 2-pole circuit, and the two center poles are linked to form the second 2-pole circuit.
How does the independent trip function work on the BQ230230?
The BQ230230 features an independent trip mechanism for its two 30A 2-pole circuits. If a fault occurs on one circuit, it trips independently without dropping power to the other. If your application requires all four poles to trip simultaneously, you will need the common trip version, catalog number BQC230230.
Is the BQ230230 suitable for HVAC equipment?
Yes, this breaker carries an HACR rating, making it approved for use with heating, air conditioning, and refrigeration applications.
Can I use the BQ230230 to replace a Westinghouse or Challenger quad breaker?
Yes, Eaton Type BR breakers, including the BQ230230, are the direct, UL-listed replacements for legacy Westinghouse, Challenger, and Bryant load centers.
