Circuit breaker schematic symbol

The circuit breaker schematic symbol is typically represented by a combination of lines and shapes that indicate its function and characteristics. Here are a few common circuit breaker schematic symbols:

1. Molded Case Circuit Breaker (MCCB): A rectangular shape with a horizontal line across the middle, and a vertical line on either side. The horizontal line represents the breaker's trip mechanism, and the vertical lines represent the contacts.
