Not a lot! If you look for 'Thyristor' or Triac devices, you will see anything from a milliamp upto some tens of milliamps. Once the device is on, the gate drive may be removed, effectivley no holding current. (note that for AC circuits, the gate will need to be re-applied at the start of every half cycle!. For DC, it just stays on.

Difference between relay and solid state relay?
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).
What solid state componet can be used as a switch to turn current on or off?
The solid state component that can be used as a switch to turn current on or off is a thyristor.
What is holding current and latching current?
HOLDING CURRENT: The minimum value of current that must be there to provide a path between anode and cathode to flow anode current and thus maintain a thyristor in the on state.0 LATCHING CURRENT: The minimum anode current required to maintain a thyristor in on-state immediately after a thyristor has be triggered on. IL>IHrate of flow of charge is known as current
What is Overload Solid State relay?
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
What is the working principle of a solid state relay?
It is an electronic switching device which controls larger load currents from small currents inside them.
What is the difference between solid state relay and safety relay?
not sure
Is a current relay same as potential relay?
current relay are using for over current low state & high state.but potential relay are related to voltage.
How latching current is different from holding current?
Latching current is the minimum amount of current required to maintain the thyristor in on-state immediately after a thyristor is turned on..and Holding current is a minimum current that is required to maintain the thyristor in on-state not allowing it to turn off.Alternative AnswerIf you are referring to a relay or contactor, when the relay is de-energised, there is a break in the magnetic circuit, so the magnetic circuit has an airgap which makes it have a high reluctance. When the relay is energised, the magnetic circuit causes the armature to close, removing the airgap and reducing the value of reluctance. So, when you first energise the relay, there must be a greater magnetomotive to overcome the higher reluctance. When the relay is closed, a lower magnetomotive force will be sufficient to overcome the lower reluctance and maintain the relay closed.
Can a 120V solid state relay stands 240V?
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
What is a pick up current?
Pick up current is the minimum current required to initiate the operation of a relay and close its contacts. It is the threshold current level at which the relay switches from its deactivated state to its activated state.
What is advantage of digital relays?
They can be used as a kind of safety switch to allow a circuit with a small current through to switch on a circuit that will hve a larger current flowing through it.
Can you replace an 3 phase solid state relay with a contactor on a 3 phase heater?
Not without other modifications. The circuits used to turn the solid state relay on will not be suitable for turning a contactor on.

What is a WAC relay on a FORD Explorer?
The WAC relay is a solid state relay usually used to control the air conditioning compressor clutch.
What is holding current?
it is the minimum current required to maintain the SCR in conducting state.
What are the terminals on a solid state relay called?
The terminals on a solid state relay are typically called input terminals and output terminals. The input terminals are used to connect the control signal that activates the relay, while the output terminals are used to connect the load that is being switched on or off by the relay.
