2. Solid-state relay - Wikipedia

   en.wikipedia.org/wiki/Solid-state_relay

   PCB mount solid-state DIL relay. A solid state relay ( SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay, but solid-state electronics contain no moving parts and have a longer operational lifetime.

3. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry ( overcurrent ). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse, which operates once and then must be replaced, a ...

4. Silicon controlled rectifier - Wikipedia

   en.wikipedia.org/wiki/Silicon_controlled_rectifier

   A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current -controlling device. The name "silicon controlled rectifier" is General Electric 's trade name for a type of thyristor. The principle of four-layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey, and Holonyak of Bell ...

5. Single-line diagram - Wikipedia

   en.wikipedia.org/wiki/Single-line_diagram

   The one-line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors are shown by standardized schematic symbols. [ 2] Instead of representing each of three phases with a separate line or terminal, only one conductor is represented.

6. How-To: Make a solid-state A/V switcher - Engadget

   Put a very small amount of solder on each pin to prep it for the wires. Cut 2 sections of 8 wires each from the ribbon cable and strip a small bit of plastic off the ends. Tin a small bit of ...

7. Fault current limiter - Wikipedia

   en.wikipedia.org/wiki/Fault_current_limiter

   Fault current limiter. A fault current limiter (FCL), also known as fault current controller (FCC), [1] is a device which limits the prospective fault current when a fault occurs (e.g. in a power transmission network) without complete disconnection. The term includes superconducting, solid-state and inductive devices.
