Abstract (en)
[origin: EP0801406A1] The controller incorporates an opening spring (25) and a coaxial closing spring (32) whose release causes compression of the opening spring. The latter drives a disc (24) fitted to the end of a rod (13) which is connected (12) to a piston carrying the moving contacts. The compression is performed after a trip by a reversible motor (44) aligned with the common axis (x-x) and driving a threaded shaft (43) integral with arms (40) bearing upon the ring (31) against which the closing spring abuts.
