Product FAQs
5 answersWhich panelboards are compatible with the Siemens BQCH2B030 circuit breaker?
The BQCH2B030 is a bolt-on molded case circuit breaker designed specifically for installation in Siemens P1, P2, and P3 panelboards.
What wire sizes and materials are accepted by the lugs on the BQCH2B030?

What is the modern replacement for the legacy Siemens BQCH2B030?
The BQCH series is a legacy product line. If you are upgrading or replacing the BQCH2B030, the newer Siemens BQD230 serves as a direct drop-in substitute for 2-pole, 30A applications in P1, P2, and P3 panelboards.
Is the BQCH2B030 suitable for all 480V electrical systems?
It is designed for solidly grounded 480Y/277V systems. Because of its slash voltage rating, it is not intended for use on ungrounded 480V Delta systems.
Does the BQCH2B030 feature adjustable trip settings?
No, this thermal magnetic breaker features fixed long-time and fixed instantaneous (LI) trip functions. The trip settings cannot be adjusted in the field.
