Selection Guide

1.	Determine inrush and sealed VA of each coil in the control circuit and VA of all other components.

2.	Total all sealed VA of all operating coils and other loads VA (determines minimal VA size required for the circuit).

3.	Total the inrush VA of all coils that are starting at the same time and all loads and coils that are running (using the regulation chart to give possible units to be used).

4.	Take VA size from step two, go to standard VA size in chart. Make sure inrush VA from chart is greater than total VA from step three. (If not, go to next larger VA size and repeat.)

If your supply voltage is stable and fluctuates less than 5%, Schneider Electric recommends you use the 90% secondary voltage column. If your supply voltage is not stable and fluctuates more than 10% we recommend you use the 95% secondary voltage column. We recommend that you never use the 85% secondary voltage column since magnetic devices lose life expectancy if they are continuously started at 85% of rated voltage.
