4.4. Choice of LV Circuit Breaker
The main role of a circuit breaker is to protect the electrical system during faults, overload and short circuit; it is designed to open a circuit automatically when the current flowing through it exceeds a predetermined value. To effectively function, the trigger circuit breaker must take into account the evolution of the receptors [11]. The LV circuit breaker can be fixed, removable, CLPG (general protection cell), removable LV circuit breaker, or TDP (Public Distribution Table). The choice of the LV circuit breaker will be from the secondary rated current.
