Relay V Contactor

[ptjw7uk]

I always thought a contactor was a device that would self power on when power is applied such that a power cut will release the contactor so it will not come on when power is resumed.
You can do the same with a relay but it will need extra contacts to do it.

No, this contactor definition is incorrect.
