How is electrical energy stored in a circuit?
Electrical energy in a circuit can be stored as potential energy, by electrons in electric fields, or associated with the kinetic energy of the moving electrons, through the magnetic field caused by the electric current.
Do Eaton circuit breakers use over-toggle mechanism?
Eaton’s residential, miniature and moulded case circuit breakers utilise over-toggle mechanism. The two-step stored energy mechanism is used when a large amount of energy is required to close the circuit breaker and when it needs to close rapidly.

What does a circuit breaker do?
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault. Why do circuit breakers trip? Circuits are designed to stay within their amp rating.
What are the components of a circuit breaker?
The contact assembly consists of the movable contact, the movable contact arm, the stationary contact and the stationary conductor. As the circuit breaker opens or closes, the fixed contact moves to close (make) or open (break) the circuit.
What is a circuit breaker frame?
The circuit breaker frame provides the rigidity and strength required to successfully deal with the interruption process and achieve the desired interrupting ratings. It insulates and isolates the electrical current in order to protect people and equipment during use or operation. Frames can be made from metal or moulded insulating materials.
What is a two-step stored energy process?
The two-step stored energy process is designed to charge the closing spring and release energy to close the circuit breaker. It uses separate opening and closing springs. This is important because it permits the closing spring to be charged independently of the opening process. This allows for an open-close-open duty cycle.
