Hi

I am looking to wire a contactor (https://www.newark.com/durakool/30c40-1023-144-5230/contactor-3pst-no-240vac-50a-panel/dp/59P3480) to a 208V 3 phase supply. The contactor coils are rated for 208V. In order for the contactor to work, should I connect one end of the contactor coil to neutral and other end to one of the lines ??

Or, should I connect the 3 lines in parallel (as each line has only 120V) and connect the output to one end of the coil and the other to neutral ??

the contactor works properly only when it gets 208 across its terminals
