That contactor you show has N.C. contacts, I imagine you need N.O.!
I assume the No 1 is a 1ph motor? or both 3 ph?
The first (1) is any small motor contactor for No 2 I would look for a Special Purpose contactor, these are used for loads with repetitive switching, that load (2) is only around 12.5 amps, 400vac contactors are fairly common as this is a common 3ph motor voltage.
