Please note that Series connection of poles divides the voltage per pole and optimises breaking capacity for high-voltage systems,as follows:
-divide the system voltage by the number of poles
- use the rated current for each pole
- use the breaking capacity of the circuit breaker for all the poles.
While Parallel connection of poles divides the current per pole and optimises the rated current for systems that do not exceed the withstand voltage of each pole,as follows:
- divide the current flowing through each pole by the number of poles
- increase the rated current.
-divide the system voltage by the number of poles
- use the rated current for each pole
- use the breaking capacity of the circuit breaker for all the poles.
