It's a mechanical relay , not a solid state relay. Powering it on is not a problem but when you power it off, the 10A of current will want to continue to flow (at the speed of light) so as the relay contacts separate at maybe 10 or 20 ms time frame , the electrons will jump the gap between the separating contacts and what will result is internal arcing (this is plasma, very hot) and will heat up the relay. If the module has a snubber circuit, this phenomenon may be surpressed. It is usually not possible to get the schematic of these modules but I can see the flywheel diode but there's no snubber cap so that could be a problem. It is possible to add an external snubber that would supress the arcing by supplying an alternate path through a series resistor/cap circuit but even so,
you are already at the maximum current for this module or a 10A SSR so I think you're pushing it on the safety side. If something bad happens at that voltage it is probably going to involve fire. You should probably look for a solution that has a higher rating so you won't be courting disaster.
