Circuit breaker isolator symbols

Here are some common circuit breaker isolator symbols:

1. Circuit Breaker Symbol: This is the most common symbol for a circuit breaker. It is a rectangular shape with a horizontal line in the middle, and sometimes a "CB" or "Circuit Breaker" label.

2. Isolator Symbol: This symbol is used to indicate an isolator, which is a device that disconnects a circuit from the power source. It is a rectangular shape with a diagonal line across it.

3. Fused Isolator Symbol: This symbol is used to indicate a fused isolator, which is a device that disconnects a circuit from the power source and also contains a fuse.

4. Molded Case Circuit Breaker (MCCB) Symbol: This symbol is used to indicate a molded case circuit breaker, which is a type of circuit breaker that is designed to be used in a variety of applications.

5. Air Circuit Breaker (ACB) Symbol: This symbol is used to indicate an air circuit breaker, which is a type of circuit breaker that uses air as the arc-quenching medium.
