PROBLEM TO BE SOLVED: To provide a relay 1 without causing a malfunction in a state of being fed with power provided at a breaker 13 side, capable of confirming the state of the interruption power to a breaker 13 side at a glance. SOLUTION: This relay 1 includes: a connection circuit 11 provided in a board always connected to a circuit 12 connected with the relay side and to a coil 14 connected with the breaker 13 side; a lock terminal 21 for making the connection circuit 11 non-connectable by being fit into the connection circuit 11 from the outside of the board; and a cover member 3 for covering the board surface of the connecting portion when the lock terminal 21 is not fit therein. This relay 1 is fit into the lock terminal 21 upon making the connection circuit 11 non-connectable and covers a fit portion 2 with the cover member 3 in the state in which power is provided to the breaker 13 side, so that an external signal is not inputted to eliminate the occurrence of a malfunction. Further, the state of the interruption of the breaker 13 is confirmed at a glance by the fit into the lock terminal 21. COPYRIGHT: (C)2008,JPO&INPIT
