I think that a 3RW4446-6BC35may be suitable but it only allows 1 start per hour.

You have to know whether you will connect your softstarter inside-delta or inline to select the correct one. In the last 4 pages of the attached file, you will fine tables for the selecten of the softstarter and also the recommended semi-conductor fuse, circuit breakes and contactors.
