Product FAQs
5 answersWhich panelboards are compatible with the Siemens HGB3B030B?
This Sentron series breaker is designed specifically for Siemens P1, P2, P3, P4, and P5 panelboards. It utilizes a bolt-on connection to securely mount directly to the panel busbars.
What are the acceptable wire sizes for the factory lugs on this breaker?
The terminal lugs accommodate 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. Installers must adhere to the torque specifications printed on the breaker faceplate to ensure a secure connection and prevent terminal overheating.
How does the fixed thermal magnetic trip unit function on this model?
The LI (Long-Time and Instantaneous) trip unit uses a bimetallic strip to provide fixed thermal protection against continuous overloads. Additionally, a fixed magnetic mechanism ensures an instantaneous trip in the event of a high-fault short circuit.
Is the HGB3B030B rated for direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for 125/250VDC systems with a maximum interrupting capacity of 42kA. Consult local electrical codes for proper wiring configurations in DC applications.
What frame class does the HGB3B030B belong to?
This device is built on the Siemens HGB frame, which is part of the broader Sentron GB and GG frame group. Verifying the frame type is critical when sourcing replacement accessories or confirming physical footprint requirements in existing enclosures.
