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.
Stay with-in the amperage capability, the voltage capability, and use a heat sink to dissipate the heat build up.
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
Nothing. An led is a solid state device.
solid-state storage
Iodine molecule has covalent bonds.
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
Solid matter is actually solid. Condensed matter is a liquid that is pressurized.
Not without other modifications. The circuits used to turn the solid state relay on will not be suitable for turning a contactor on.
Air Compressor solid state relay
The difference will be in their physical state i.e., solid and liquid state and in their chemical composition. Solid fuels that are used are the filling inside bombs i.e,. gun powder. Liquid fuels used are RDX etc.
The WAC relay is a solid state relay usually used to control the air conditioning compressor clutch.
the difference between the three states of matter is that a solid has a definite shape and volume. a liquid does not have a definite shape but does have a definite volume. gas does not have either.
If you mean between hard drives and ssd's (solid state drives), then you need to read the wikipedia page on Solid State Drives, it has a comparison of the two technologies.
