This unit comprises three independent rectangular prismatic parts, fitted into each other by superposition, the upper part of which constitutes an independent unopenable cover, on each of the upper faces of which appear hollow turrets at each one of their corners, in the interior of which are accessible the service and couple terminals for the performance of measurments of the characteristics of the current. Fitted on this upper part is the intermediate part, which is the head of the unit, which presents at the bottom of its hollow interior, four notches for passage of the upper ends of the service and couple terminals. The lower part, which is the body of the unit, presents a peripherical recess on the upper edge for the fitting of the unit head, showing at the bottom of its hollow interior, four notches placed in proximity to the corners for passage of the lower ends of the service and couple terminals plus a central notch for passage of the grounding terminal.

L'appareil comprend trois parties prismatiques rectangulaires indépendantes, s'emboîtant l'une dans l'autre par superposition, la partie supérieure constituant un couvercle indépendant qui ne peut s'ouvrir, sur les faces supérieures duquel apparaissent des tourelles creuses à chacun de leurs coins, à l'intérieur desquelles on a accès aux bornes de branchement et de couplage pour mesurer les caractéristiques du courant. Emboîtée dans cette partie supérieure, la partie intermédiaire est la tête de l'appareil, laquelle présente au fond de son intérieur creux quatre encoches pour faire passer le bout supérieur des bornes de branchement et de couplage. La partie inférieure, qui est le corps de l'appareil, présente un évidement périphérique sur le bord supérieur pour recevoir la tête de l'appareil, montrant au fond de son intérieur creux quatre encoches placées à proximité des coins pour faire passer le bout inférieur des bornes de branchement et de couplage, plus une encoche centrale pour faire passer la borne de mise à la terre.
