Product FAQs
6 answersWhat types of equipment are compatible with the SND6B100LIG circuit breaker?
This 1000A unit mount breaker is designed for use in Siemens switchboards, Type S5 and SPP power panelboards, and motor control centers.
What does the LIG designation mean on this Sentron series breaker?
The LIG trip function indicates that the solid-state electronic trip unit provides adjustable protection for Long-Time overload, Instantaneous short circuits, and Ground-Fault conditions.
How does the ground-fault (G) function improve system safety?
The ground-fault protection detects unwanted low-level current flow to the ground. This helps prevent severe equipment damage and reduces the risk of electrical fires before a full short circuit occurs.
Are there specific lug kits required for installing this ND-frame breaker?
Yes. Depending on your wire size and configuration, you can use compatible ND-frame lug kits such as the 3TA4N8500 for 250 to 500 kcmil conductors, or the 3TA3N8750 for 500 to 750 kcmil conductors.
Can the continuous current rating be adjusted on the SND6B100LIG?
Yes, the electronic trip unit allows you to adjust the continuous current rating to a percentage of the 1000A maximum. This provides flexibility for changing loads without requiring a breaker replacement.
Is this breaker part of the Siemens Sensitrip family?
Yes, the SND6B100LIG is an ND-frame solid-state breaker from the Sentron Sensitrip family. It utilizes an electronic trip unit rather than a traditional thermal-magnetic mechanism.
