Problems solved by technology

[0002] The miniature leakage circuit breaker is a miniature circuit breaker with leakage protection. The miniature circuit breaker has short-circuit protection and overload protection. The short-circuit protection is realized by the electromagnetic tripper. In order to realize the leakage protection, the miniature leakage circuit breaker needs to add a leakage trip To realize the leakage protection, in order to arrange the leakage release, the volume of the small leakage circuit breaker is bloated

Abstract

The invention relates to a release for a miniature circuit breaker. The release comprises a movable iron core, a static iron core, an ejector rod, an iron core sleeve, an electric leakage coil and a current coil, wherein the electric leakage coil is wound outside the iron core sleeve, the current coil is wound outside the electric leakage coil, the number of turns of the electric leakage coil is larger than that of the current coil, and the electric leakage coil and the current coil are wound outside the iron core sleeve at the same time. The functions of short-circuit protection and leakage protection can be realized through using one release, the size of the miniature circuit breaker caused by the number of the release is effectively reduced, and the purpose of miniaturization of the size of the miniature leakage circuit breaker is realized.

Description

technical field [0001] The invention relates to a tripper for a miniature circuit breaker. Background technique [0002] The miniature leakage circuit breaker is a miniature circuit breaker with leakage protection. The miniature circuit breaker has short-circuit protection and overload protection. The short-circuit protection is realized by the electromagnetic tripper. In order to realize the leakage protection, the miniature leakage circuit breaker needs to add a leakage trip To realize the leakage protection, in order to arrange the leakage release, the volume of the small leakage circuit breaker is bloated. Contents of the invention [0003] In view of this, the object of the present invention is to provide a tripper for a miniature circuit breaker that can realize both short circuit protection and leakage protection. [0004] In order to achieve the above object, the present invention adopts a tripper for a small circuit breaker, including a moving iron core, a static...
