Iee breaker symbols

IEE (Institution of Electrical Engineers) breaker symbols are a standardized set of symbols used to represent electrical circuit breakers in diagrams and drawings. Here are some common IEE breaker symbols:

  1. Main Breaker: A circle with a horizontal line across it, indicating a main circuit breaker.

  2. Distribution Breaker: A circle with a diagonal line across it, indicating a distribution circuit breaker.

  3. Residual Current Breaker (RCD): A circle with a diagonal line and a horizontal line across it, indicating a residual current breaker.

  4. Earth Leakage Breaker: A circle with a diagonal line and a vertical line across it, indicating an earth leakage breaker.

  5. Moulded Case Circuit Breaker (MCCB): A rectangle with a horizontal line across it, indicating a moulded case circuit breaker.

  6. Air Circuit Breaker (ACB): A rectangle with a diagonal line across it, indicating an air circuit breaker.

  7. Oil Circuit Breaker (OCB): A rectangle with a vertical line across it, indicating an oil circuit breaker.

  8. Vacuum Circuit Breaker (VCB): A rectangle with a horizontal line and a diagonal line across it, indicating a vacuum circuit breaker.

  9. Gas Circuit Breaker (GCB): A rectangle with a horizontal line and a vertical line across it, indicating a gas circuit breaker.

  10. Arc Fault Breaker: A circle with a diagonal line and a wavy line across it, indicating an arc fault breaker.

These symbols are widely used in electrical engineering and are recognized globally. However, it's always a good idea to check the specific standards and conventions used in your region or industry.
