Operating mechanism for tripping a voltage circuit breaker

Abstract

An operating mechanism for tripping a circuit-breaker, the operating mechanism comprising a coil having a first terminal and a second terminal, means for generating a first electric impulse, and means for creating, from the first electric impulse, a second electric impulse delayed from the first electric impulse and applied between the first terminal and the second terminal of the coil, characterized in that the means for creating the second electric impulse comprise a delaying circuit and a switch connected in series with the coil, the delaying circuit having an input connected to an output of the means for generating a first electric impulse and an output which delivers the second electric impulse, said second electric impulse being a command signal of the switch.
