Built for heavy-duty commercial environments, this 30A, 2-pole MCCB delivers consistent thermal-magnetic overcurrent protection. It operates efficiently on 240VAC and 480Y/277VAC systems, utilizing a trip-free mechanism for enhanced safety. The unit mounts into Siemens P1, P2, and P3 panelboards via a sturdy bolt-on connection. Facilities looking for current equivalents can use the BQD230 as a substitute for this model. It features a 65kAIC rating at 240V and is HACR certified.
Which 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?
The load-side lugs on this breaker accept 14 to 6 AWG copper (Cu) wire or 12 to 6 AWG aluminum (Al) wire.
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.
