Embodiment Construction
[0052]With reference to the above figures, the present invention relates to an electrical switching apparatus 1 for low or medium voltage applications.
[0053] For the purposes of the present invention, the term "low voltage" (LV) relates to operating voltages below 1 kV AC and 1.5 kV DC, while the term "medium voltage" (MV) relates to operating voltages above 1 kV up to a few tens of kV (for example, 70 kV AC and 100kV DC) working voltage.
[0054] The switchgear 1 comprises a cabinet 2 comprising a plurality of walls 21, 22, 23, 24, 25 defining an internal volume.
[0055] Referring to the normal installation position, the cabinet 2 includes a horizontal base wall 21, a horizontal top wall 22 in an opposite position relative to the horizontal base wall 21, and a plurality of vertical walls ( Figure 1-2 ).
[0056] These vertical walls include: a front wall 23 from which an operator can access the interior volume of the cabinet; a rear wall 24 in an opposite position with ...
