Electrical Symbols For Low Voltage Circuit Breakers

The electrical symbol of Low voltage pole mounted circuit breaker is usually represented by a rectangular box with some marks or graphics inside to indicate its function.

The following are several common electrical symbols for low-voltage circuit breakers:

1. Air circuit breaker: There are three parallel lines in the middle of the rectangular box to represent the main contacts, and an arc with an arrow above one of the lines represents the arc.

2. Magnetic circuit breaker (also known as fuse): There is a fuse or a thermal release element with an arrow in the rectangular box to represent overload protection.

3. Miniature circuit breaker: There is a thermal release element for overload protection and a manually operable switch in the rectangular box.

4. Fire-resistant circuit breaker: There is a fuse for overload protection and a switch for short-circuit protection in the rectangular box.

These symbols are just some common examples, and different electrical standards and manufacturers may use slightly different symbols to represent low-voltage circuit breakers. Therefore, in specific applications, please refer to the relevant electrical drawings or equipment manuals to determine the exact symbol representation.
