Problems solved by technology

[0002] The existing 2P leakage circuit breaker has the functions of leakage tripping, overload tripping, and short circuit tripping, but its wiring mode cannot be reversed. Once reversed, the test circuit will be charged, which will affect the performance of the product. In addition, there is no leakage indication. Therefore, after the circuit breaker is disconnected, it is not known what caused the disconnection, which brings trouble to maintenance

Abstract

The invention relates to a 2P electric leakage circuit breaker, in particular to a 2P electric leakage circuit breaker with positive and negative wiring and electric leakage indication. In the technical scheme adopted by the invention, the 2P electric leakage circuit breaker is characterized in that a first mounting cavity is formed in the common end of a first shell and a second shell; an electric leakage release and a current transformer are arranged in the first mounting cavity; the current transformer is electrically connected with the electric leakage release; a second mounting cavity isformed between two adjacently attached side edges, namely a first side edge and a second side edge, of the first shell and the second shell; and an electric leakage tripping indication unit is arranged in the second mounting cavity and comprises an electric leakage lock catch, an indication piece and a torsion spring. By adopting the scheme, the defects in the prior art are overcome, and the novel2P electric leakage circuit breaker which is simple in structure and reliable in action and has a positive and negative wiring function and an electric leakage indication function is provided.

Description

technical field [0001] The invention relates to a 2P leakage circuit breaker, in particular to a 2P leakage circuit breaker with forward and reverse wiring and leakage indication. Background technique [0002] The existing 2P leakage circuit breaker has the functions of leakage tripping, overload tripping, and short circuit tripping, but its wiring mode cannot be reversed. Once it is reversed, the test circuit will be charged, which will affect the performance of the product. In addition, there is no leakage indication. Therefore, after the circuit breaker is disconnected, it is not known what caused the disconnection, which brings trouble to maintenance. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a novel 2P leakage circuit breaker with simple structure, reliable operation, positive and negative wiring functions and leakage indication. [0004] In order to achieve the above object, the present invention adopts...
