Product FAQs
8 answersHow should I use the 1200A rating when selecting this breaker?
The Siemens 3VA6712-6HN31-2AA0 has a rated current of 1200A. Use that rating when coordinating breaker selection with circuit load, conductor ampacity and protection settings; adjustable trip settings must be evaluated separately from the rated current.
Which system voltages can I select this breaker for?
The breaker is rated for 240VAC, 480VAC and 600VAC. Select it for the circuit's operating voltage, then check the interrupting rating at that voltage because fault-interruption capability changes with voltage.
How do I check whether its interrupting rating is adequate?
Compare available fault current at the installation point with the breaker’s interrupting rating: 100kA at 240VAC, 65kA at 480VAC or 35kA at 600VAC. The available fault current must not exceed the applicable rating.
What does the adjustable electronic LSI trip do?
The electronic trip has adjustable protection with long-time, short-time and instantaneous functions. Long-time protection addresses sustained overcurrent, while short-time and instantaneous functions address higher fault currents with delayed or immediate operation. Coordinate settings with conductor protection and the system protection scheme.
What mounting arrangement and dimensions should I plan around?
This is a unit-mount breaker measuring 16.00 in high, 9.00 in wide and 6.00 in deep. Use those dimensions to plan the installation layout, and account separately for conductor routing and working space.
What temperature range should I consider for the installation location?
The temperature rating is -25C to 70C. Evaluate the temperature where the breaker will operate, including local heat buildup, when choosing its installation location.
Does this breaker meet UL 489 requirements?
The breaker has UL approval and conforms to UL 489, the standard for molded case circuit breakers. Use this certification when checking the project's circuit-breaker approval requirements.
How should I arrange the phase conductor connections?
Use one of the breaker's three poles for each phase conductor in the three-phase circuit. Plan the conductor layout around these three phase connections.
