Abstract : The patent describes a three-phase power interruption apparatus which includes a controllable bidirectional semiconductor interposed in each respective phase between a source of power and a load. Each of the semiconductors is controlled by a respective trigger voltage supply which is connected to receive a voltage from the source having a relatively leading phase. An oscillator driven counter and associated relay circuitry causes the trigger supplies to cease providing the trigger voltage for a predetermined interval so that the semiconductors correspondingly interrupt the provision of power to the load during that interval.
