Hello good day! I would like to give me your advice with my problem right now. Can a 5v relay SRD-05VDC-SL-C can manage to carry 15-17 amps? data sheet shows that max VA is 3750 VA, I'm not sure if its applicable with the 5v 10amp variant.
hope that you guys can help me with my problem.
Seriously doubt it, Chinese part specs are usually inflated. The form C contact arrangement is supposedly good for 15 amps at 250vac but that is for a purely resistive load. There is no way I’d use that part at that rating. Songle does have 30 amp devices more suitable for a 17 amp load but...
What is the load you’re trying to switch? A motor, a heater, a what? That is a huge factor in equation.
There appears to be 3 versions of the relay, 7A, 10A, 15A.
Why would you expect the 10A version to be good for 17A ?
17A would be outside the rating for even the 15A version.

No. The maximum switching current is 15A, you must not go over that value.

No, that is only true for the 15A type.
A lot of these relays do not have the track clearances for switching mains type voltages ( despite the claims) any way and I’d agree the specs seem over rated . ( there is a lot dodgy cheap gear out there)
There are also categories AC/1, AC/3 etc which relate to duty and load type .
To switch a 20A 240v circuit I ended up using a contactor and switched that with a relay .
Make sure you comply with local regulations too ( ie are you allowed to do it ) and understand fusing, cables and earthing .
I've been switching 7-10 amps at 12v for couple years now on a 10A songle on one project but's a pulse that lasts about 100 mS. So far nothing bad has happened.
Looks like they're copies of 5V Osram or panasonic relays:

Osram rates theirs for 1A.

Please note that the 250v 10 A rating on the panasonic is for the contact. The leads on them leave a little to be desired for higher voltage and current application.
