When the electromagnetic contactor 16 is excited, the contact 3 closes and the power is supplied. supplied to the load. 4 is an overcurrent relay, and when an overcurrent is detected by the overcurrent relay 4, the contact 12 is opened and the electromagnetic contactor 16 is de-energized. 5 is a terminal for connecting the load, 6 and 7 are a bipolar switch 8 and a protective fuse for the transformer 9, respectively, which will be described later, 8 is a manual bipolar switch that selectively switches between the test position TEST and the normal position NORMAL, and 9 is a control circuit. step-down transformer, 10,
11 is a control circuit protection fuse inserted into the secondary side of the transformer 9, 12 is a contact of the overcurrent relay 4 that cuts off the power to the control circuit when the overcurrent relay 4 detects an overcurrent, and 13 is for the load. A manual switch for turning on the power, 14 a manual switch for turning off the load power, 15 a remote or automatic control signal for turning off the load power, and 16 a contact 3 of the magnetic contactor.
17 is an auxiliary contact for self-holding of the electromagnetic contactor 16, and 18 is a remote or automatic control signal for turning on the load power source.

送られる。 In such a circuit, normally power switch 2 is turned on and bipolar switch 8 is set to NORMAL on the right side.
Set it to . Then, when the manual switch 13 or the control signal 18 is turned on, the electromagnetic contactor 16
is excited and the contact 3 and the auxiliary contact 17 are turned on, and even if the manual switch 13 is subsequently turned off, the auxiliary contact 17 forms a self-holding circuit for the electromagnetic contactor 16, and power is not supplied to the load connection terminal 5. Sent.
