What is a Solid State Relay?
An SSR, or solid state relay, is an electronic switch that contains no moving parts and that has the same use as an electromechanical relay.
In an SSR a small control signal controls a larger load current or voltage. Solid state relays consist of:
- A sensor which responds to a control signal
- A solid state electronic switching device
- A coupling mechanism
The switching device is used in order to switch power to the load circuitry. The coupling mechanism enables the control signal to activate the switch without any moving parts.

Choosing the Right Solid State Relay:
When you are looking for the right solid state relays, you can filter the results by various attributes with the FutureElectronics.com parametric search:
by Maximum Contact Current (1.1 mA to 500 A), Maximum Isolation Voltage (200 V, 1500 V, 2500 V, 3750 V, 4000 V, 5000 V,…)
and Output Voltage (up to 800 V) to name a few. The parametric filters on our website can help refine your search results depending on the required specifications.
Applications for Solid State Relays:
Solid state relays are ideal for repetitive applications due to the absence of moving parts. Some applications for solid state relays are:
- Medical
- HVAC
- Professional food equipment
- Theatrical lighting
- Industrial machinery
- Control panels
- Elevators and lifts
- I/O interfaces

WIRING DRAWING :
Order Model Number Explaination:
OPERATION NOTICE:
1. Resistive load could not exceed 60% of the rated current.
2.Inductive or capacitive load could not exceed 40% of the rated current.
3.Electric machine load could not exceed 20% of the rated current.
4.Proper radiator adapted to the working requirement of solid state relay should be equipped, the allowance should be widened when the load radiating condition is not so good. Short-circuit load is not allowable.
5.Over Current Protection: over current and short circuit are the main reasons for permanent damage of output controllable silicon in the SSR, and using fast fuse and air switch is one of methods for over current protection, fuse is also available for small capacity.
6.Over Voltage Protection: It can adopt parallel voltage-dependent resistance(MOV), the MOV area decides the absorption power, while its thickness decides the protective voltage value, generally, 471/10D voltage-dependent resistance for 220V series SSR, 681/10D voltage-dependent resistance for 380V series SSR, 821/10D voltage-dependent resistance for 480V series SSR.
