Problems solved by technology

[0003] However, if the above image 3 In the prior art shown above, it is necessary to install the main circuit breaker and the branch circuit breaker before wiring. If the number of circuits increases, the weight will increase. If the wiring space is lost due to the existence of the circuit breaker, the workability will deteriorate.
In addition, when disassembling the branch circuit breaker after wiring, it is necessary to unscrew the primary side terminal of the branch circuit breaker and pull out the connecting wire from the terminal part. If there are too many connections, it will be difficult to operate.

Abstract

In a definite structure of electric distributor, a main breaker and a branch breaker are mounted on a slideway which is fixed on the distributor, the fixed part of the said branch breaker slide way is fastened onto the above mentioned slideway and the said branch breaker primary side terminal is inserted into the main circuit fastened with screws. The above mentioned main circuit is fixed on a cover to be fixed on the distributor.

Description

technical field [0001] The invention relates to a switchboard, in particular to a switchboard comprising a panel, a guide rail fixed on the panel, and a main circuit breaker and a branch circuit breaker installed on the guide rail. Background technique [0002] image 3 Indicates the fixed construction of an existing branch circuit breaker. The fixed structure of the existing branch circuit breaker is as follows: image 3 As shown, the guide rail 12 is fixed on the plate 11 , and the main circuit breaker 13 and the branch circuit breaker 14 are installed on the guide rail 12 . The connection of the primary-side terminal to the branch circuit breaker 14 is performed with wires or copper bars. [0003] However, if the above image 3 In the prior art shown above, it is necessary to install the main circuit breaker and the branch circuit breaker before wiring. If the number of circuits increases, the weight will increase. If the wiring space is lost due to the existence of the ...
