Enhed til en flerpolet afbrydelsesindretning med dobbelt kappe og afbryder, som omfatter denne

摘要

In order to take maximum advantage of the modularity provided by a multipole circuit breaker with double enclosure (100), a new architecture is proposed. The outer case (48) of the switchgear apparatus (100) is formed directly when assembly of the breaking device (600) is performed by juxtaposition and securing between single-pole breaking units (10), spacers (46) and side walls (50), trip device (7) and cover (64). The spacers (46) can thus be used for various functionalities, and in particular to modify the external aspect of the switchgear apparatus (100) or the nature of the trip device (7) in delayed manner.
