Answer :

Final answer:

Fuses and circuit breakers are vital symbols in control schematics, acting as safety devices to prevent electrical hazards by interrupting circuits when overloaded.


Explanation:

Fuse and circuit breakers are commonly used symbols in control schematics. Fuses consist of a metal strip with a low melting point that breaks the circuit in case of excessive current, while circuit breakers are automatic switches that open the circuit when needed.

  1. A fuse is a safety device that interrupts the circuit when overloaded.
  2. Circuit breakers provide the advantage of easy restoration after tripping due to excess current.
  3. Both fuses and circuit breakers play crucial roles in preventing electrical hazards in circuits.
