The present invention relates to a circuit breaker for a distribution panel, and more specifically, a plurality of insertion grooves are formed stepwise so that a plurality of bus bars can be inserted on one side of the main body of the circuit breaker, and the insertion groove is A space portion is formed in each side of the formed body so that the coupling members can be installed, and the bus bars are tightly coupled to the coupling member to facilitate the installation of the distribution panel and the arrangement of the wirings connected to the circuit breaker. The invention relates to a breaker for a distribution panel that can reduce cost by reducing the width.

As is well known, a general distribution panel is installed in the form of a rectangular parallelepiped in which the front is opened. A case (not shown) is hinged so as to be open / closed in a case where the molded case is embedded in a wall of the room. The main circuit breaker is connected to the inside of the case, and a switch for each branch circuit, that is, a plurality of earth leakage breakers, is arranged in parallel at a position where the main circuit breaker is connected to the branch circuit and the branch circuit breaks from the main circuit breaker. It supplies the indoors smoothly and at the same time controls the flow of current.

As described above, the conventional main circuit breaker 100 installed in the distribution panel is mounted on the main body 10 and the main body 10 that is injected and molded into the synthetic resin as shown in FIG. It consists of a trip device 20 for shorting the power supply and a plurality of components installed in the main body 10. The trip device 20 is provided with an extension of a three-phase wire 30 of a predetermined length.

Subsequently, as shown in FIG. 2, each of the three-phase wires 30, which are extended and installed, is deformedly bent in the distribution panel 200 and connected to the bus bar 40 having a splinter shape that is installed inside the distribution panel 200. In addition, a plurality of earth leakage circuit breakers 300 are connected to the plurality of bus bars 40 to which the three-phase wires 30 are connected, respectively, and are applied to the main circuit breaker 100 by a separate wire 30 '. Each of the circuit breakers 300 is distributed and applied.

However, in order to connect the three-phase wire 30 extending from the main circuit breaker 100 to the plurality of bus bars 40 separately installed in the distribution panel 200, the distribution panel 200 has a very narrow interior. Connection and installation is very difficult to reduce the efficiency of the work and the distribution panel 200 by the width of the main circuit breaker 100 and the bus bar 40 to be spaced apart at a predetermined interval to one side of the main circuit breaker 100 Of course, a wider range of molding, as well as the required length of the wire 30 is long, resulting in a rise in the manufacturing cost accordingly caused a number of problems, such as lowering the competitiveness of the product.

Therefore, in order to solve the above problems, the present invention forms a plurality of insertion grooves on one side of the circuit breaker main body installed in the distribution panel at regular intervals, and forms a predetermined space inside one side of the main body where the insertion groove is formed. A plurality of coupling members connected to one end of a three-phase electric wire connected to the trip device in the space part are closely mounted to insert a busbar bar shaped into the insertion groove and to be coupled to the coupling member so that power can be applied. By improving the efficiency of the work by facilitating the installation of the distribution panel in a short time, by reducing the width of the distribution panel by minimizing the length of the wire and the installation length of the bus bar provided to significantly reduce the manufacturing cost to improve the competitiveness of the product It is an object of the present invention to provide a circuit breaker that can be improved.

In order to achieve the above object, the present invention is applied to an indoor distribution board, and in a circuit breaker for controlling the flow of power by a tripping device mounted on one side of a main body, a predetermined space portion formed inside one side of the main body is partitioned. Each step is formed by step, the space portion is provided with a coupling member for connecting the one end of each of the three-phase wire connected to the trip device, one end of the bus bar in the form of a slipper is inserted on one side of the main body is installed. Characterized in that it is formed integrally with the insertion groove to be fixed.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

3 is a front view schematically showing a circuit breaker for a distribution panel according to the present invention, and FIG. 4 is a cross-sectional view schematically showing a circuit breaker for a distribution panel according to the present invention and FIG. 5 is an installation of a circuit breaker according to the present invention. It is a schematic diagram showing the state.

As shown, the circuit breaker 100 of the present invention is installed inside the case 210 of the distribution panel 200 to control the power applied to the indoor in the outdoors, the main body 10 and the main body 10. It is largely composed of a trip device 20 to be installed, the electric wire 30 of a predetermined length, the bus bar 40 and the coupling member 50.

The main body 10 is injected and molded in a predetermined shape, but forming a predetermined space portion 12 inside one side, the space portion 12 is an independent space stepped by a plurality of partitions (14) And a plurality of insertion grooves 16 are integrally formed on one side of the main body 10 in which the space 12 is formed.

The trip device 20 is mounted on the circuit breaker 100 main body 10 as known to cut off the power supply in response to a short circuit caused by an overcurrent or an overload. In the present invention, the main body 10 The trip device 20 is suitably fitted to the main body 10 so as to be firmly fastened and fixed.

The coupling member 50 is provided with a state in which elasticity is applied to one side by bending and processing a metal plate having a predetermined thickness so as to have a "" shape, and at least so that the three-phase wires 30 can be connected and fixed, respectively. It is provided with a plurality of three or more are inserted into the space portion 12 formed by the partition wall 14 of the main body 10, respectively.

The circuit breaker 100 configured as described above is firmly installed in the case 210 of the distribution panel 200, and then a bus bar 40 having a selvedge shape is formed in the plurality of insertion grooves 16 formed on one side of the main body 10. When each end is inserted, one end of the bus bar 40 is tightly inserted into the coupling member 50 mounted to the space 12 and is firmly fixed by the elasticity of the coupling member 50.

Subsequently, when the bus bar 40 is fixed, a plurality of earth leakage breakers 300 are installed in the case 210 of the distribution panel 200, and then a plurality of electric wires are provided separately from the earth leakage breakers 300 and the bus bars 40. Connect to 30 'to allow power to be applied.
