Description
Designed for high-capacity power distribution, this 1200A Siemens MCCB utilizes a Sensitrip III unit for reliable electronic trip sensing. The 3-pole breaker features adjustable Long-Time and Instantaneous (LI) pickup settings to optimize system coordination. It is compatible with Siemens Sentron P4 and P5 panelboards, as well as SB1, SB2, and SB3 switchboards. For modern upgrades, it is replaced by the SND6B120LI. Rated at 65kAIC at 240VAC, the SND69120A requires separate lug kits.Specifications

Product FAQs
7 answersWhat panelboards and switchboards are compatible with the SND69120A circuit breaker?
This breaker is designed for use in Siemens Sentron Type P4 and P5 panelboards, as well as SB1, SB2, and SB3 switchboards.
What does the LI trip function indicate on this breaker?
The LI designation means the electronic trip unit features adjustable Long-Time and Instantaneous pickup settings, allowing for precise coordination with your electrical system's time-current curve.
What type of electronic trip unit is installed in the SND69120A?
This breaker utilizes a Siemens Sensitrip III solid-state electronic trip unit for reliable low voltage power distribution protection.
What is the difference between the Siemens SND6 and ND6 frame circuit breakers?
The SND6 frame utilizes a solid-state electronic trip unit (Sensitrip), whereas the standard ND6 frame uses a traditional thermal-magnetic trip unit. Both share the same physical dimensions and mounting requirements.
Can the SND69120A be reverse fed?
Yes, this circuit breaker is acceptable for reverse connection applications.
What are the wire size requirements for the lugs on this 1200A breaker?
The standard lug configuration requires four 250 to 500 kcmil copper or aluminum conductors per phase.
Which lug kit is typically used for the SND69120A to accommodate 500 kcmil wire?
The TA4N8500 lug kit is commonly used, providing four barrels per phase for 250 to 500 kcmil Cu/Al conductors.
