Object of the present invention is to provide a controller for distribution apparatus which prevents extension of power failure. In accordance with the controller for distribution apparatus related to the present invention, when a short circuit accident, for example, occurs in a control circuit for distribution apparatus, a breaker for distribution opens, an auxiliary coil becomes unexcited condition, and power failure is caused, but, an auxiliary contact point of the unexcited auxiliary coil closes in the other control circuit for distribution apparatus so as to excite a closing coil, and consequently, the other control circuit starts its operation immediately. Accordingly, extension of the power failure can be prevented and reliability of power supply can certainly be maintained.
