Yeah, its a counterfeit SSR. I've used one before and that relay required 12VDC on the input to reliably switch the load. It's been crippled in most every aspect. The new specs for your relay would be something like:
[color=teal][b]Label True spec[/b][/color]
3-32VDC 12-24VDC?
40A 20A?
24-380VAC 48-240VAC?
