An explosion-proof switchgear apparatus comprises an enclosure housing a carriage mounted on a guide and coupled by a pivot pin to a chassis which accommodates electric devices and the movable part of a separable contact system whose fixed part is secured to the enclosure for interaction with the movable part. The apparatus includes a coupling unit mounted on the pivot pin and it is secured to the chassis whose opposite end has a vertical slot. The apparatus is also provided with a guiding retainer means installed at the same enclosure portion, where the fixed part of the separable contact system is mounted, and received into the vertical slot.
