...Relay AC SSR of Three Phase Description of AC SSR Relay What is the difference between Solid-state Relays and Contact Relays? Answer Solid State Relays use semiconductors for no-contact operation. Solid-state Relays are not very different in operation from Contact Relays (Electromagnetic Relays). Solid-state Relays, however, consist of electronic parts with no mechanical contacts. Therefore, Solid-state Relays...
