Dear All,
I need to use a tripping mechanism for AC current typically in range of 150 to 200A. I tried one SSR which had rating of 200A. However, even when around 120A flows through it, the SSR heat sink (along with fan) temperature rises to around 70Degree Celsisus.
Are there any SSR for use in continuous operation in this current range. Or can we parallel the SSR for the same. Also I would like to know if there any triacs which have similar rating. I checked mouse, but could find triace up to 88A.
What are the other low cost options for achieving this. Thanking you.
