Relay with core conductor and current sensing

An electromagnetic relay adapted to be connected in series with a power source AC and an AC load, the relay comprising an operating coil (14) to which a drive current controlled manner to close and release armor contactor applies ( 24) of the relay, the armature contactor (24) comprising an element (22) which normally separates the armature contactor driving coil and a first electrical contact (26, 26 '') supported by the armature aforementioned contactor; and a second electrical contact (27, 28) which is adapted to contact with said first contact when the drive coil (14) is in a state that attracts the armature contactor (24) or is adapted to make contact with the said first contact when the actuator coil (14) that is in a state that releases the armature (24); characterized in that the second contact (27, 28) is connected to a núcleoconductor (18) passing through an axial hole of the coil aforementioned drive (14) carrying the conductive core (18) load current the said AC load when the coil drive aforesaid closes the aforementioned armor contactor; and by the fact that a current sensor load (38) has input terminals connected to a winding of the coil aforementioned actuator (14) adapted to collect a representative induced voltage of the load current carried by the core aforementioned driver .
