Abstract
The utility model relates to a low-voltage electrical apparatus for the overcurrent protection and the short-circuit protection, especially relating to a breaker with the leakage protecting function. A leakage protecting breaker comprises a casing, a line connecting seat, a live conductor, a zero line, a double gold slice, a contact component, a switch component which are arranged in the casing in sequence, an electromagnetic component and an arc extinguishing sleeve. A leakage protecting mechanism is arranged on the extend end whose width is the same as the width of the casing. The utility model has the advantages that because the leakage protecting mechanism is arranged on the extend end whose width is the same as the width of the casing, the width of the utility model is unchanged, more breakers can be installed in an illumination boxe with the same width. The leakage protecting breaker has the advantages of high installation efficiency and good reliability. In addition, a test button and a circuit arranged can detect that whether the function of leakage protecting of the leakage protecting breaker normal or not.
Description
Technical field
The utility model relates to the low-voltage electrical apparatus of a kind of overcurrent protection and short-circuit protection, relates in particular to a kind of circuit breaker that also has creepage protection function.
Background technology
At present; the circuit breaker primary structure that is used for the overcurrent protection of low-voltage circuit or short-circuit protection is as follows: be disposed with junction block at shell; the bimetallic contact assembly; switch module; electromagnetic assembly; between the contact end of bimetallic assembly and electromagnetic assembly, go back and be provided with arc-extinguish chamber; as need earth leakage protective; also to increase earth leakage protective mechanism; prior art constructions is earth leakage protective mechanism of stack in the shell that increases width; the shortcoming of this structure is that the quantity of the circuit breaker that can install in the certain lighting case of width spaces will reduce about one times, and poor reliability.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides that a kind of width is narrow, installation effectiveness is high, the earth leakage circuit breaker of good reliability.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of earth leakage circuit breaker; comprise housing and set gradually therein junction block, live wire, zero line, two gold plaque, contact assembly, switch module and electromagnetic assembly and arc-extinguish chamber, be provided with earth leakage protective mechanism with the elongated end of width at housing.
The beneficial effects of the utility model are: owing at the same width elongated end of housing earth leakage protective mechanism is set; width of the present utility model does not change, thereby in the lighting case of same width, more circuit breaker can be installed; has the installation effectiveness height, the advantage of good reliability.In addition, whether the testing button of setting and circuit can normally detect creepage protection function of the present utility model at any time.
