Adequate protection means a two-step process. Limitation ramping of AC inrush current in conjunction with a delay-on-make DC relay load isolator. Starts off with load isolation, when softened inrush i...
Well, that relay is beyond MY lab budget. If I wanted to protect a lower amperage DC circuit against inrush, especially one with a transformer or inductor based power supply, I might choose an Omron relay and a couple of thermistors. A lot depends on how much current is being passed along.
