的とするものである。The earth leakage breaker is not provided with an auxiliary switch for all, but is attached only to a necessary one according to the specifications of the presence or absence of the auxiliary switch.
Therefore, in the conventional earth leakage breaker according to the above-mentioned mounting device, the auxiliary switch is mounted on the side plate at the same time when the opening / closing mechanism is assembled.At that time, the work of mounting the support plate on the side plate is performed by screwing. It was troublesome to tighten, and the consistency of work with the one without auxiliary switch was impaired, which was a factor to reduce work efficiency. Further, if the support plate is fixed to the side plate in advance before the assembly of the opening / closing mechanism, two types of side plates are stocked depending on the presence or absence of the auxiliary switch, which causes a problem of cost increase. 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。By the way, the power supply circuit of the earth leakage detecting section in the earth leakage circuit breaker is generally connected to the load side main circuit of the earth leakage circuit breaker, and power is supplied from the power supply side main circuit only when the earth leakage circuit breaker is in the on state, and is in the off state. Then, the power is cut off. On the other hand, in a distribution board, etc., when 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 breaker on one side The reverse connection may be forced to connect a load to the side terminal. However, in such a reverse connection, even if the earth leakage breaker is turned off, the power supply of the earth leakage detection unit is not cut off, which is not preferable. Therefore, if the leakage detection unit is connected to the power source via the contact of the auxiliary switch, even if the connection is reversed, it is possible to cut off the power supply of the leakage detection unit by turning off the auxiliary switch contact at the same time as turning off the leakage breaker.

The earth leakage detector 22 is composed of a zero-phase current transformer and an electronic circuit that amplifies its output. When an earth leakage is detected, the trip electromagnet 6 is excited to drive the armature 7 to form a part of the opening / closing mechanism 17. Push the trip bar 23 to the right in FIG. Although not shown, since the trip bar 23 locks the right end of the latch member 20 in FIG. 6, the latch member 20 rotates clockwise in FIG. 6 to open the opening / closing member 21 when the trip bar 23 is pushed. . As a result, the movable contact 12 is separated (trip operation), 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 energizing current becomes an overcurrent state, bimetal 1
Since 3 bends to the right in FIG. 6 and pushes the trip bar 23, the earth leakage breaker also trips in this case. The power supply circuit of the earth leakage detector 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 earth leakage breaker is off.

The base is fitted and fixed to the case from above. Therefore, according to the present invention, when assembling the auxiliary switch to the main body of the earth leakage breaker, additional work such as caulking and screw tightening is not required, and the auxiliary switch that is previously attached to the base and is in stock is required. Therefore, a ground fault circuit breaker with an auxiliary switch can be easily configured simply by combining it with a ground fault trip device, and because the auxiliary switch is installed, the consistency of the work of assembling the ground fault circuit breaker is hindered and work efficiency is improved. It never drops. Also, if the earth leakage detector is connected to the power supply via the contact of the auxiliary switch, even if the main circuit wiring of the earth leakage breaker is reversely connected, the earth leakage detector will be connected via the auxiliary switch contact when the earth leakage breaker is off. The power of can be cut off.
