Product FAQs
7 answersWhat panelboards and switchboards is the Siemens SHND69120ANTH compatible with?
This ND frame breaker is designed for installation in Siemens P5 panelboards, S5 power panels, and Sentron switchboards.
What does the 'H' in the SHND69120ANTH catalog number signify?
The 'H' indicates that this circuit breaker is 100% rated. It can carry its full 1200A continuous current rating safely without the standard 80% derating requirement, provided it is installed in a properly sized and ventilated enclosure.
Is the SHND69120ANTH suitable for reverse-feed applications?
Yes. Because it is assembled with a non-interchangeable trip unit, this breaker meets UL requirements for reverse connection applications, allowing power to be fed from either the line or load side.
What type of trip unit is installed in the SHND69120ANTH?
It features a Sensitrip III solid-state electronic trip unit with LSI (Long-Time, Short-Time, and Instantaneous) functions for precise, microprocessor-based circuit protection.
Does the SHND69120ANTH include ground fault protection?
No. This specific catalog number features LSI (Long-Time, Short-Time, Instantaneous) functions only. Sentron breakers with ground fault protection (LSIG) will include a 'G' in the catalog number suffix, such as SHND69120ANGTH.
Can I swap the trip unit on the SHND69120ANTH to change its amperage?
No. This specific model is built with a non-interchangeable trip unit, meaning the 1200A rating is fixed and cannot be swapped out in the field.
Is the SHND69120ANTH a current production model?
This is a legacy Sentron series breaker typically used to replace or maintain existing installations. For entirely new builds, Siemens generally recommends transitioning to the newer 3VA series breakers.
