Stay with-in the amperage capability, the voltage capability, and use a heat sink to dissipate the heat build up.
All solid state relays are relays, but not all relays are solid state relays. There are three basic kinds of (protective) relays I know of: electromechanical (rely on induced voltages and currents to spin disks or energize solenoids), solid state (built with solid state parts - basically prerequisites to microprocessors), and microprocessor based relays (fancy computers).
a relay that detects the amperage the motor is drawing when the motor dwaws too much to drops out the coil voltage to shut down motor and prevent damage
It is an electronic switching device which controls larger load currents from small currents inside them.
The solid state component that can be used as a switch to turn current on or off is a thyristor.
Solid state devices.
not sure
No.If you are looking of a relay that will allow 240V, many suppliers sell a SSR that will handle up to 280V AC. Most are triggered by 3-32v dc.Just google: solid state relay OR solid state contactor
Not without other modifications. The circuits used to turn the solid state relay on will not be suitable for turning a contactor on.

The WAC relay is a solid state relay usually used to control the air conditioning compressor clutch.
Wire it as shown in the diagram at the link below.
A small light bulb is often used to test a solid state relay (SSR). That is because a SSR needs a minimum load of at least 0.1 amps in order to operate. Using a meter does not provide a sufficient load.

There is a WOT A/C relay - Wide Open Throttle A/C relay - that shuts off the air conditioning compressor when you floor the gas pedal The wac relay is a solid state relay usually used to control the air conditioning compressor's clutch.
