Also I found this interesting video a a SSR maker, explaining how you have to install it:
I discovered that you need to heat sink it because it will use so much power ! In the video it says the SSR is wasting 1W per Amp of current passing through it: this is huge
Unless you want to create heat, I do not see any good reason to use this; The Kilovac EV200AAANA from Tyco uses only 1.7W when the contact is closed, and for whatever amount of current passing through this contact, and it can be a lot !

So I guess I will keep using Kilovac for my build :
It is an investment but a good one for safety - reliable cut off - and efficiency - 1.7W used only -
