的とするものである。Not all the earth leakage breakers are provided with auxiliary switches, but only those which are necessary according to the specification of the presence or absence of the auxiliary switches.
Therefore, in the earth leakage circuit breaker according to the conventional mounting device, the auxiliary switch is mounted on the side plate at the same time as the assembling of the opening and closing mechanism. Even if it is tightened, it is troublesome, and the consistency of the work with the one without the auxiliary switch is hindered, which is a factor to reduce the work efficiency. Further, if the support plate is fixed to the side plate in advance before assembling the opening / closing mechanism, two types of side plates are stocked depending on the presence or absence of the auxiliary switch. there were. Therefore, an object of the present invention is to provide an earth leakage breaker with an auxiliary switch in which the auxiliary switch can be easily assembled.

る。[0006] The power supply circuit of the leakage detector in the earth leakage breaker is generally connected to the load side main circuit of the earth leakage breaker, and power is supplied from the power supply side main circuit only when the earth leakage breaker is in the on state, and is turned off. Then the power is cut off. On the other hand, in a distribution board or the like, if multiple earth leakage breakers are distributed on both sides of the power line and arranged in the same direction, connect the power line to the load side terminal of the earth leakage In some cases, a reverse connection in which a load is connected to the side terminal is required. However, in such a reverse connection, even if the earth leakage breaker is turned off, the power of the earth leakage detection unit is not shut off, which is not preferable. Therefore, if the leakage detecting unit is connected to the power supply via the contact of the auxiliary switch, the power of the leakage detecting unit can be cut off by turning off the auxiliary switch contact simultaneously with the turning off of the leakage breaker even in the case of reverse connection.

The leakage detecting unit 22 includes a zero-phase current transformer and an electronic circuit for amplifying the output. When a leakage is detected, the tripping electromagnet 6 is excited to drive the armature 7 and constitute a part of the switching mechanism 17. The trip bar 23 is pushed rightward in FIG. Although not shown, the trip bar 23 locks the right end of the latch member 20 in FIG. 6. Therefore, when the trip bar 23 is pressed, the latch member 20 rotates clockwise in FIG. 6 to open the opening / closing member 21. . As a result, the movable contact 12 is separated (trip operation), and at the same time, the operation unit 20a is separated from the actuator 1a, and the auxiliary switch 1 sends an off signal. In addition, when the conduction current becomes an overcurrent state, the bimetal 1
3 is bent rightward in FIG. 6 and pushes the trip bar 23, so that the earth leakage breaker trips also in this case. The power supply circuit of the leakage detecting unit 22 is connected to the relay conductor 1 on the load side via the contact of the auxiliary switch 1 which is turned off when the leakage breaker is turned off.
5 is connected.

Therefore, according to the present invention, when assembling the auxiliary switch to the earth leakage breaker main body, additional work such as caulking and screw tightening is not required, and the auxiliary switch previously attached to the base and stocked is required. The earth leakage breaker with the auxiliary switch can be easily configured simply by combining it with the earth leakage tripping device in accordance with the situation. It does not drop. Also, if the leakage detector is connected to the power supply via the contact of the auxiliary switch, the leakage detector will be connected via the auxiliary switch contact when the leakage breaker is turned off even if the main circuit wiring of the leakage breaker is reversely connected.
