What main contactor to use for AC system with regen?
I have searched around and i am finding it difficult to select a main contactor.
The main concern i have is that most contactors seem to have polarity preffernces. The main contacts being labelled with + and - or A1 and A2. Because the current can flow in either direction in an AC setup with regen i don't want to damage the main contactor.
Several data sheets for contactors mention things like magnetic blowouts which i have heard don't like reversed current flow.
Anybody with an AC motor setup like to share their contactor experiences?
