Product FAQs
6 answersWhat type of panelboards and switchboards accept the SND6A120LI?
The SND6A120LI is an ND frame breaker designed to mount in Siemens Sentron panelboards, including S4, S5, P4, and P5 models. It is also compatible with Siemens SB1, SB2, and SB3 switchboards and motor control centers.
What does the "LI" stand for in the SND6A120LI trip unit?
The "LI" indicates that the electronic trip unit provides adjustable Long-Time and Instantaneous protection. This allows for precise coordination and customization based on the specific load requirements of your electrical distribution system.
How does the electronic trip unit on the SND6A120LI differ from a standard thermal-magnetic breaker?
Unlike traditional thermal-magnetic breakers that rely on fixed bimetal strips and electromagnets, the SND6A120LI uses a solid-state Sensitrip electronic trip unit. This provides more accurate current sensing and allows you to adjust the trip characteristics to better coordinate with upstream and downstream devices.
Can the SND6A120LI be reverse fed?
Yes, the SND6A120LI is suitable for reverse feed applications. Because the electronic trip unit is factory-installed and non-interchangeable, it meets UL 489 requirements for reverse feeding.
Can I swap the trip unit on the SND6A120LI in the field?
No. To comply with UL standards for reverse-feed suitability, the electronic trip unit on the SND6A120LI is non-interchangeable and cannot be removed or swapped in the field.
What is the difference between the SND6A120LI and the ND63B1200?
Both are 1200A, 3-pole ND frame breakers, but they use different trip technologies. The SND6A120LI features a solid-state electronic trip unit with adjustable settings, while the ND63B1200 uses a standard thermal-magnetic trip unit.
