Product FAQs
7 answersWhich Siemens panelboards are compatible with the SND6A100LI circuit breaker?
This ND-frame breaker is designed for use in Siemens Sentron panelboards, specifically types S4, S5, and SPP, as well as compatible Siemens switchboards.
Can the trip settings on the SND6A100LI be adjusted in the field?
Yes, this breaker features an electronic trip unit with adjustable Long-Time (L) and Instantaneous (I) trip functions, allowing you to fine-tune the protection curve for your specific load requirements.
How is the SND6A100LI mounted within a panel or enclosure?
This is a unit-mount circuit breaker with a feed-thru connection type. It bolts directly to the mounting pan or structure rather than plugging onto a busbar.
What is the frame size of the SND6A100LI?
It is built on the Siemens ND frame, which has a maximum capacity of 1200A, though this specific breaker is factory-configured with a 1000A electronic trip unit.
Are lugs included with the SND6A100LI?
This breaker is configured for lug terminals. When ordering, verify if the specific lug kit is included or needs to be sourced separately based on your wire size and material (copper or aluminum).
What does the LI in the SND6A100LI catalog number indicate?
The LI designates the trip functions of the electronic trip unit. It includes adjustable Long-Time (L) protection for overloads and Instantaneous (I) protection for short circuits.
Is the SND6A100LI a 100% rated circuit breaker?
No, this is a standard 80% rated circuit breaker. For continuous loads, the circuit should be designed so the continuous current does not exceed 800A (80% of its 1000A rating).
