A compact power circuit breaker (1) has a molded insulative casing (3) providing the structural support and electrical isolation for the pole mechanisms (11) mounted in cavities (9) in the casing and the operating mechanism (33) mounted to the front of the casing. A grounded barrier (17) between the pole mechanisms (11) and the operating mechanism (33) protects the operator actuating push bottons controlling the operating mechanism and accessible through a molded insulative cover. Preferably, the grounded barrier (17) is sandwiched between a rear section (5) of the molded casing containing the pole cavities and a forward section (7) to which the operating mechanism is secured. The grounded barrier (17) is connected to an electrically conductive pan (61) extending under the molded insulative casing which also houses electrically grounded linkages coupling the operating mechanism to the vacuum interrupters of the pole mechanisms. A vented air gap (65) between the rear section (5) of the molded insulative casing and the grounded barrier (17) minimizes erosion of the molded insulative casing in the event of an arc penetrating the casings to the grounded barrier.

Cette invention concerne un disjoncteur compact dont la coque isolante moulée fait office de support structurel et qui assure l'isolation électrique des mécanismes de pôle montés dans les cavités de ladite coque et du mécanisme de déclenchement à l'avant de la coque. Un écran mis à la masse entre les mécanismes de pôle et le mécanisme de déclenchement protège l'opérateur lorsqu'il sollicite les boutons poussoirs qui commandent le mécanisme de déclenchement et qui sont accessibles au travers du couvercle isolant moulé. L'écran à la masse est de préférence pris en sandwich entre une partie arrière de la coque moulée qui renferme les mécanismes de pôle et une partie avant sur laquelle est monté le mécanisme de déclenchement. Cet écran est relié à un bac électriquement conducteur au bas de la coque isolante moulé, qui renferme les tringleries mises à la terre reliant le mécanisme de déclenchement aux interrupteurs à dépression des mécanismes de pôle. Un interstice d'air ouvert sur l'extérieur, situé entre la partie arrière de la coque isolante moulée et l'écran de mise à la masse, réduit les risques d'érosion dus à la formation éventuelle d'un arc entre la coque et l'écran.
