We have a test facility where we test fans. I need to determine the maximum motor sizes we can start DOL and star/ delta with the electric panel in this facility.
This is the information that I have:
1. The voltage can be selected as 220, 400 or 525V.
2. On the 220V panel there is a Moeller P7-63 contactor, the 400 and 525V have Moeller P10-400 contactors.
3. The 525V is achieved by means of a transformer, the only information I have on this is a nameplate which read: Primary: 380V 304A
Secondary: 525V 220A
Can anybody help?
