Product FAQs
8 answersWhat enclosures or panelboards are compatible with the SCND69800ANGT?
This ND frame breaker is designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers.
What wire sizes do the lugs on the SCND69800ANGT accept?
The lugs accommodate 250 to 500 kcmil copper or aluminum conductors. Due to the 800A rating, multiple conductors per phase are required to safely meet ampacity requirements.
What does the LSIG designation mean on this breaker trip unit?
LSIG indicates that the electronic trip unit features adjustable settings for Long-Time, Short-Time, Instantaneous, and Ground-Fault protection. This allows for precise coordination with other protective devices in your electrical system.
Can the SCND69800ANGT be reverse fed?
Yes, this breaker is suitable for reverse feed applications, allowing you to wire the incoming line connections to either the top or bottom terminals.
What is the difference between Siemens SCND and CND breakers?
The SCND features a solid state electronic trip unit, while the standard CND utilizes a thermal-magnetic trip unit. Both are current limiting ND frame breakers with identical physical dimensions and interrupting capacities.
Does the SCND69800ANGT provide personnel ground fault protection?
No, the ground fault function in the LSIG trip unit is designed for equipment protection against damaging fault currents. It is not rated for Class A personnel protection.
Does the SCND69800ANGT require a specific mounting hardware kit?
Yes, as a bolt-on ND frame breaker, it requires specific Siemens mounting hardware when installed in Sentron panelboards or switchboards. The exact hardware kit depends on your specific enclosure type.
Is the SCND69800ANGT a current limiting circuit breaker?
Yes, the C in the SCND prefix designates it as a fuseless current limiting breaker. It is designed to interrupt high fault currents quickly without the need for external fuses.
