Abstract
A device for interlocking at least two single- or multipole circuit breakers, of which:—a first circuit breaker, suitable to be fixed to a mounting plate of the first and second circuit breakers; —a second circuit breaker, suitable to be fixed by virtue of fixing means to the first bracket and to be supported thereby;—an interlocking element, provided with a contoured body that is operatively coupled to the second bracket so that it can move with respect to it, the interlocking element being suitable to be rigidly connected to the second bracket, by virtue of locking means, in a chosen position in which it interacts operatively with at least the first opening/closure lever in a condition that corresponds to the opening of the first circuit breaker, preventing its movement and preventing the circuit breakers from being closed simultaneously.
