Let be the first connection point,
The first connection point is grounded through a first switch means that closes when an abnormality occurs in the load equipment, and a third resistor and a fourth resistor, which are equal to each other, are connected in series between the power supply side wires of the earth leakage breaker. and the third resistor and 4
The connection point between the resistors is the second connection point, and the connection point between the first connection point and the second connection point or the ground is the first connection point.
A load equipment abnormality characterized in that the third resistor, the fourth resistor, and the lamp are built in the earth leakage breaker side, and the third resistor, the fourth resistor, and the lamp are connected via a second switch means that is closed in conjunction with the second switch means. Earth leakage breaker with cutoff function and display. (2) Claim (1) of the utility model registration claim characterized in that the third resistor and the fourth resistor are configured to be connected between the power supply side wires when the earth leakage breaker is opened. earth leakage breaker. (3) The second switching means is omitted and the lamp is connected directly to the first connection point and the second connection point, and instead is connected between each commercial voltage line, the first resistor and the second resistor. The earth leakage circuit breaker according to claim (1), which is a registered utility model, is characterized in that the two are connected via third switch means which are connected and closed in conjunction with the first switch means. (4) The first switch means is omitted, and instead, each commercial voltage line, the first resistor, and the second resistor are connected to each other in conjunction with the second switch means to close the connection in the event of an abnormality in the load equipment.
