Power Power Outages after the call prohibit a re-closure circuit

  
Power outages after the call prohibit re-closure circuit, can avoid the use of electrical appliances after the power grid
Power Power Outages after the call prohibit a re-closure circuit - schematic

and forgot to turn off electricity, then call caused an accident when. Use relays or contactors can be easily shown 13-77 (a) shown below, but the relay coil to coil power consumption, and when the load power is large, the need to use contactor control, not only cumbersome but also noise. If dual thyristor as a non-contact switch, can solve the problem,
