ANSIIEEE Standard Device Numbers 1 - Master Element 2 - Time Delay Starting or Closing Relay 3 - Checking or Interlocking Relay 4 - Master Contactor 5 - Stopping Device 6 - Starting Circuit Breaker 7 Rate of Change Relay 8 - Control Power Disconnecting Device 9 - Reversing Device 10 - Unit Sequence Switch 11 Multifunction Device. In the design of electrical power systems the ANSI Standard Device Numbers ANSI IEEE Standard C372 denote what features a protective device supports such as a relay or circuit breaker. However today most of the symbols are internationally standardized.
There are two methods for indicating protection relay functions in common use. Whether it is a complex control system on a machine tool or a simple across-the-line motor starter the need to recognize and understand these symbols becomes more important. Electrical symbols are used to represent electrical and electronic devices in schematic diagrams.
