The MCTC4825JLB that you have linked is a temperature controller rather than just a solid state switch.
I use SSR's on my machines to control spindle, laser, etc. and I find the a.c. type of SSR more useful than the d.c. types. The SSR's that I use are like those in the attached picture.
This type of SSR can be operated by 5 Volts at <10mA and can switch up to 480Vac at 25 Amps (large heatsink required for large currents). The big advantage of these a.c. SSR’s is that they switch at the zero crossing point of the mains waveform so can switch loads without creating noise spikes as may be caused by a standard relay.
Wire sizes required are related to Voltage and Current (Watts) and would be the same for an SSR as a standard relay.
Hope this helps.
