摘要

Monitoring system of the control elements of the circuit breakers and correct fulfillment of the functions thereof, characterized in that it consists of the conjunction of two relays, the first of instant and instant relapse and the second of instantaneous energization but timed relapse, which their coils are connected in series with respective resistors, forming at the output of them connections to the fuse of a supply pole of the circuit breaker, while the second relay has its coil connected on the other hand to the contacts of the first relay, composing the output of them and together with the output of the coil of the first relay a set of connection sockets to the coil of the circuit breaker or switch and to the fuse of the other pole of the supply of this, so that connected this system monitor the continuity of that coil of the circuit breaker or breaker the good condition of the power fuses of the same and the existence of power supply voltage suitable ion for the operation of said trip coil, the second relay making the signaling of the existence of faults due to the warning influence of the first relay on it.
