500VA Toroid - Relay or Contactor?

[Tom J]

I use the softstart, via 240v switch, than contactor via fail safe latching, but after reading few post will try MCB type D without softstart - will upload results.

Meantime here is my softstart



It switch primary coil via 4x10W resistors just to kill in rush current and after second small relay bypassing resistors before they became too hot. This delay is enough for peak to go down.
This is only inconvenience for toroid trafo I know.
