Hi,
I just bought an Omron MY2 DPDT relay to fix an equipment. From the window, the contact rating as follow..
5A 240 VAC
5A 28 VDC
I don't understand why is there such a significant difference between AC and DC at the contacts?
When I google, the explanation is that DC current requires higher contact rating than AC but why so?
Is this because of the resistance difference between AC and DC?
Vincent.
