Product FAQs
7 answersWhich Siemens panelboards accept the LGB3B015B circuit breaker?
This bolt-on breaker is specifically designed for installation in Siemens P1, P2, and P3 panelboards.
How is the LGB3B015B installed into the electrical system?
It utilizes a bolt-on connection for the line side to mount directly to the panelboard bus. The load side features lugs that accept 14 to 6 AWG copper or 12 to 6 AWG aluminum conductors.
What are the specific interrupting capacities for this 15A breaker across different system voltages?
The breaker is rated for 100kAIC at 240V, 65kAIC at 480Y/277V, and 14kAIC at 600Y/347V, making it suitable for high capacity commercial and industrial distribution systems.
How does the LGB frame differ from standard GG frame breakers?
While it shares the same internal design features as the GG frame, the LGB frame is specifically configured with a bolt-on line end for panelboard mounting applications rather than standard cable connections.
What protection functions does the thermal magnetic trip unit provide?
The fixed thermal and fixed magnetic trip unit provides standard LI (Long-Time and Instantaneous) protection, safeguarding against both sustained overloads and short circuits.
What is the maximum frame size for the LGB3B015B?
This breaker is built on a 125A maximum frame within the Siemens Sentron GB/GG family, but this specific model is factory set for a 15A continuous current rating.
Is the LGB3B015B suitable for HVAC or lighting applications?
Yes, this breaker is both HACR rated for heating, air conditioning, and refrigeration equipment, and HID rated for high intensity discharge lighting circuits.
