Abstract
A technique is provided for controlling an operator in a circuit such as a relay circuit. The operator may be a coil in an electromagnetic relay. The coil is energized only when current through a leakage current suppression circuit is sufficient to exceed a predetermined threshold. The leakage current suppression circuit is operative to prevent energization of the operator, or to deenergize the operator, when the current is below the threshold, within a range anticipated for leakage current through the circuit.
