Circuit Breaker Control Schematic Explained
The circuit breaker operating mechanism controls the opening or closing of the switches. As the mechanism rises to the "open" position (breaker tripping), the switch is forced to "make" or "break" contacts. When the mechanism is pulled closed (breaker ON), the switch resets and returns the contacts to their deactivated position.
