ABSTRACT:
An electrical recloser apparatus includes a tank (10) having bottom, top and side walls (18, 22, 16) which define an interior, sealed space (14), and a current interrupter (44) disposed within the sealed space (14) and including a pair of relatively movable contacts (46, 48) which are movable between a closed, current-carrying position and an open, current-interrupting position. A control assembly (30) is provided for electronically controlling the opening and closing of the contacts (46, 48), the control assembly (30) initiating operation of the contact moving means (58) to move the contacts (46, 48) to the open position in response to a fault current sensed by a sensing means (66), and initiating operation of the contact moving means (58) to move the contacts (46, 48) to the closed position after each one of a predetermined number of opening operations. The control assembly (30) is mounted on the bottom wall (18) of the tank (10) exterior of the sealed space (14), and the side wall (16) of the tank (10) preferably extends beyond the bottom wall (18) to provide a solar shield for the control assembly (30). Further, the control assembly may be mounted in a housing (32) which is removably supported adjacent the bottom wall (18) of the tank (10) to permit removal of the control assembly (30) for replacement or reprogramming.
