Product FAQs
6 answersWhich Siemens panelboards and switchboards accept the SND69100A circuit breaker?
This 1000A Sentron series breaker is compatible with Siemens Sentron Type P4 and P5 panelboards, as well as SB1, SB2, and SB3 switchboards.
What is the accepted wire range for the SND69100A breaker?
The breaker lugs accept four 250 to 500 kcmil copper or aluminum (Cu/Al) conductors per phase.
How is the SND69100A mounted in a panelboard?
This breaker features a bolt-on connection type, providing a secure mechanical and electrical installation directly to the busbars of compatible Siemens Sentron panelboards and switchboards.
What adjustments are available on the SND69100A electronic trip unit?
The LI trip function code indicates that the solid-state electronic trip unit features adjustable rotary switches for Long-Time (continuous current) and Instantaneous pickup settings, allowing you to fine-tune the protection profile.
Can the SND69100A be used to upgrade older ND frame breakers?
Yes, the SND69100A utilizes the standard ND frame footprint (16 x 9 x 6 inches), allowing it to serve as an electronic-trip replacement for older 1000A thermal-magnetic ND frame breakers in compatible Siemens enclosures.
What precautions should be taken when setting the trip unit dials on the SND69100A?
When adjusting the Long-Time and Instantaneous settings, ensure the rotary switches are properly set to their mechanical detent (click stop) positions. Dials left between detents can cause the breaker to default to unintended values, resulting in nuisance tripping.
