  • Each of the poles E, F, G, H and J being provided for a rating of 3200A, it is thus possible build a 4000A four-pole circuit breaker. Since the current normally flowing through the neutral is lower than that flowing through the other phases of the network, there is no need to provide an extended connection area for the neutral. On the other hand, for reasons of insulation, it is preferable to separate the pole associated with the neutral from the other poles and to insert the unused elementary compartment I between them.

  • Three of the central poles, for example M, N and O are connected in parallel, the compartment elementary P remaining unused. The size of this circuit breaker is then greater than the size of 2 standard poles placed in parallel.
