Early Mechanical Circuit Breakers

The journey of circuit breaker technology began with mechanical circuit breakers, which relied on physical movement to open and close the electrical contacts.

Mechanism and Functionality

Mechanical circuit breakers used a simple mechanism where an electromechanical actuator would trip the circuit in response to excessive current, physically separating the contacts to interrupt the current flow.

Limitations

While effective for basic...
