PURPOSE:To eliminate an excess installation space and to facilitate the wiring by fitting a control input display device to a 3-phase solid-state relay SSR main body. CONSTITUTION:A case 6 of a control input display device 51 is fitted and fixed to a cover 7 of a 3-phase SSR 100, a terminal 3 of the control input display device 51 is overlapped on the control terminal 1 of the 3-phase SSR 100 and both are tightened and connected by a terminal screw 1. In connecting a control signal connection lead from the control power supply to the control terminal 1 of the 3-phase SSR 100, when a control input signal is given, a display light 4 is lighted to display that the control input signal in inputted to the 3-phase SST 100.
