An electrical switching device for low voltage circuits comprising an enclosure having a front wall, a rear wall, a first lateral wall, a second lateral wall, a lower wall and an upper wall that define a volume for containing the members of said switching device, said enclosure comprising:
- a first section that defines a first housing space for a switching unit that comprises one or more electrical poles, each of said electrical poles comprising at least one fixed contact and one moving contact, mutually couplable/decouplable;
- a second section that defines a second housing space for a control mechanism of the moving contacts of said electrical poles;
- a third section that defines a third housing space for one or more accessory devices of said switching device; An electrical switching device is characterized in that said front wall comprises a first shaped portion and a second shaped portion adapted to respectively close the housing spaces defined by said second and third section, at said front wall, said first and second shaped portion being mechanically separable from one another. |
