Abstract:
1. An electromechanical relay adapted to be situated in series with a source of AC power and an AC load, the relay comprising an actuator coil to which an actuator current is controllably applied for closing and releasing a contactor armature of the relay, the contactor armature including means normally biasing the contactor armature away from the actuator coil and a first electrical contact carried on said contactor member; a second electrical contact adapted to make contact with said first contact when the actuator coil is in a state that is either moved towards said contactor armature, or is biased away from the contactor armature, the second contact being connected to a core conductor that passes through an axial bore of said actuator coil, the core conductor carrying load current to said AC load when said actuator coil closes said contactor armature; and a load current sensor having input terminals connected to a winding of said actuator coil for picking up an induced voltage representative of the load current carried on said core conductor.
