Why solid state relays are solid

Why solid state relays are solid

Answer:

You know the electromagnetic relay has a contact, the coil is energized after the contact action to make the circuit connected, so it is operating state, and solid-state circuit breaker is no contact, the use of thyristor as a switch, when the control voltage signal On the conduction, and no contact action, which has a relay function, not a relay, so give it a solid circuit breaker name, and electromagnetic relays to be distinguished.
