Abstract (en)

[origin: US6124558A] PCT No. PCT/EP99/01508 Sec. 371 Date Nov. 19, 1999 Sec. 102(e) Date Nov. 19, 1999 PCT Filed Mar. 9, 1999 PCT Pub. No. WO99/49490 PCT Pub. Date Sep. 30, 1999A rotation activated circuit breaker with a leading auxiliary switch, in which the auxiliary contacts of the auxiliary switch are actuated before the main contacts. An actuator element is provided, which contains a drive pinion that is rotation actuated by an actuating mechanism and a longitudinally movable first gear rack, which engages with the drive pinion and actuates the auxiliary switch. Furthermore, a second gear rack, which lags behind the first gear rack in the closing direction, and an output pinion, assigned to the second gear rack, which is connected to a drive shaft for the breaking mechanism of the circuit breaker, are provided. The tooth pitch of the output pinion and the second gear rack is greater than the tooth pitch of the drive pinion and the first gear rack so that the total rotation angle of the drive pinion and output pinion is the same over the full closing motion of the actuating mechanism.
