Electrical cut-off device e.g. circuit breaker, for cutting direct current in photovoltaic electricity generation station, has actuating mechanism with reversal unit to move mobile contact bridge between contact and separating positions

摘要

The device (30) has a mobile contact bridge (33) including an elongated body and an end on which a contact region (36) is positioned to cooperate with a contact area (37) of a fixed contact (32). An actuating mechanism includes a reversal unit (50) to move the mobile contact bridge between a contact position in which the contact region of the bridge is in contact with the contact area of the fixed contact, and a separating position in which the bridge is rotated about a pivot axis by an angle of rotation, where the pivot axis is parallel to a longitudinal axis (X).
