the technical information on products is vanishing rapidly.
Its not always the best - especially for a numpty like me. I'm learning though.

It’s switching the mains to the vfd so will need to be rated for at least that current - definitely more than 1 amp!Paul you have picked a DC coil contactor and your control circuit appears to be AC, as it’s fed off the secondary of the 24 v transformer. You could probably pick a cheaper lower current contactor also as your current is less than an amp so don’t need 25A contacts.
Do you have a transformer? Your pictures showed a dc power supply which you were going to use instead??But... I do still need to sort out a rectifier and smoothing capacitor to convert the 24V AC out of the transformer to 24V DC?
I’d say the exact opposite - I’ve worked with industrial controls for years and have only seen a handful of ac control circuits - the vast majority of stuff I do is 24 dc.In the motor control world I would say 24vac control circuits are far more common than dc stuff, esp as if you have dc coils you need to consider reverse emf protection. Speaking as someone who works in hvac controls.

You have one.
Sorry! DC
