High voltage relays are used to transfer power for high voltage and high frequency applications.

Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications

Motor contactors are relays with large current capacity for connecting and disconnecting a motor from the power supply.

Relay sockets are devices that accept relays, electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit

Power supplies are devices that produce AC or DC power.

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other

Protective relays and monitoring relays detect or monitor for abnormal power system conditions
