We all know that the basic function of earth leakage circuit breaker and the general low-voltage circuit breaker, on this basis, however, the relevant principles of the protection device using residual operating current is interrupted at the crucial moment, play a protective circuit, at the same time the most the main thing is to protect the personal safety. The reason is called leakage circuit breaker is used in leakage protection. This article mainly talk about something of brands and models under leakage circuit breaker, the principle of selection.

The reason why this article will mainly see the other day there the customers a DZ47LE breaker DZ47 circuit breaker. In fact, the most direct models difference two letters "LE" LE representatives of leakage protection circuit breaker, and the brands and models of the circuit breaker, which means that this is a leakage circuit breaker. Here a little supplement under the other, is a circuit breaker molded case circuit breakers and earth leakage circuit breaker is not in conflict, as we used DZ20L series leakage circuit breaker, from the the material appearance on it, it is a molded case switch , but functional, it is also a leakage switch different classification. If you want to understand the specific meaning of some leakage circuit breaker brands and models, be the first to study under some of our factories Model Description, it will have a rough understanding.

Leakage circuit breaker is modular in design, the product compact but fully functional. The core component of the operating mechanism, zero sequence current transformer, electromagnetic release, leakage tripping. The zero sequence current transformer is the most important part. Leakage release points electromagnetic and electronic two, the difference between them is the leakage current of the former can be operated directly by the release main switch, after the latter leakage current through the electronic amplification line amplifiers release action can to operate the main switch.

Leakage circuit breaker models, the above also said that, with LE word models, specific self-closing different models, there is a different brand. Of those generic models, major brands, including our production specifications as well, such as the most common DZ47-63, DZ47-100 and other models.

Finally, a little under the brand. Leakage circuit breaker as a common model of the circuit breaker, basically all the circuit breaker manufacturers will be involved in abroad, or more reliable Schneider and Siemens. Domestic or imitation-based, the lack of a truly epoch-making products, and many manufacturers, competition is relatively intense. Some manufacturers addition to those generic models also have their own R & D production models, such as our SRM series circuit breaker in some products, such as SRM18LE leakage circuit breaker, relatively speaking, is a good brand models.

Some information leakage circuit breaker is mainly in a future article, we will introduce more foreign brands, including models for everyone, we want to help.
