PURPOSE:To obtain a system linkage apparatus which simplifies a circuit and can be made small and lightweight. CONSTITUTION:The title apparatus is provided with a semiconductor switch 16 which is connected in parallel with a loop circuit breaker 11, with a voltage detection circuit 27 which outputs a signal when the voltage across a system A and a system B exceeds a prescribed value and with a control circuit 29 which turns on the semiconductor switch 16 and which turns off the loop circuit breaker 11 under the AND condition of the output signal of the voltage detection circuit 27 and the semiconductor-switch ON command signal of a command part 22. |
