Product FAQs
5 answersWhich Siemens panelboards accept the LGB3B060B circuit breaker?
This molded case breaker is designed for direct installation into Siemens P1, P2, and P3 panelboards. It utilizes a bolt-on mounting configuration for secure phase integration in commercial and industrial power distribution applications.
What conductor sizes are supported by the LGB3B060B terminals?
The factory-installed lugs are dual-rated for both copper and aluminum conductors. They accept 8 to 1/0 AWG copper (Cu) wire and 8 to 2/0 AWG aluminum (Al) wire. Always refer to the breaker faceplate for proper termination torque specifications.
Is the trip unit on this 60A Sentron breaker adjustable?
No, the LGB3B060B features a fixed thermal and fixed magnetic trip unit. Both the long-time (L) and instantaneous (I) trip protection levels are factory calibrated and cannot be adjusted in the field.
Can the Siemens LGB3B060B be applied in DC power systems?
Yes, this 3-pole Sentron series breaker is rated for direct current systems. It provides a 14kA interrupting capacity (AIC) when applied at 125VDC or 250VDC.
What is the short circuit interrupting rating for this breaker at 480V?
In 480VAC or 480Y/277VAC systems, the LGB3B060B delivers a 65kAIC short circuit interrupting rating. When applied to 240VAC systems, the interrupting capacity increases to 100kAIC.

The breaker was exactly what I needed, and it came within a couple days. The price was in line of what it should’ve been. This was my third purchase from Super Breakers. I will definitely use them again in the future.
