There is some circuit using Start Star - Run Delta together with Softstart (Motor 75 Kw) ..(Power circuit below)
May be can explore the idia for some project.
Could anybody give me some suggestion about this Power circuit please
How to calculate or select an appropriate Magnetic Contactor?
(2 type of magnetic contactor)
What is the difference between type 1 and type 2 of magnetic Contactor
How to calculate or select an appropriate overload relay?
K6 in this picture is essential or not?
(someone told me using for good protection.
Some circuit from some book use 3 overload (add more below main cB)
1. Without Softstart K1 + K2 +K3 + K4
K1 + K2 = MAIN CONTACTOR
K3 = STAR CONTACTOR
K4 = DELTA CONTACTOR
2. With Softstart
K2 + K4 + K5 + K6 on at the same time ( K1 & K3 OFF )
Thank you very much
