ABSTRACT:
The present invention relates to unloading relays mounted in modulation circuits of the allocated power by modification by telecontrol of the tripping threshold of the breaker. A preceding signal or the telecontrol signal of the level of the breaker detects, by a modified contactor 15, the assigned power (by the relay 12) of the unloading relay 16. The invention permits adapting unloading relays to modulation networks of the allocated power.
