This standard promotes the naming of product models, and formulates them as the industry's unified naming method, and also considers the naming method of enterprises, which can reflect the autonomy and model exclusive rights of manufacturing enterprises. In addition, in terms of the meaning of the code in the model, due to the continuous development of the product, the form feature code and variety feature code have been partially improved and supplemented. The implementation of this standard is the standardization of the naming model of low-voltage switchgear products in my country according to varieties and specifications, which plays an important role in the production and use of products, catering cooperation and maintenance. Under the general title of "Methods for compiling each product model", it includes the following parts: JB/T3752 in "Low-voltage complete switchgear and control equipment Part 1 (ie JB/T3752.1): Low-voltage complete switchgear 1 Part 2 (ie JB/T3752.2): Electric control equipment. This standard is first formulated.
Appendix A of this standard is a prompt appendix.
This standard is proposed and managed by the Technical Committee for Standardization of Electric Drive Complete Control Equipment . The drafting units of this standard: Tianjin Electric Drive Design Institute, Beijing Switch Factory. The main drafters of this standard: Xue Ruihuai, Lu Guoping. I

This standard specifies the model compilation method of low-voltage complete switchgear. Applicable to rated voltage AC not exceeding 1000 V, low-voltage complete switchgear with a frequency not exceeding 1000Hz and a DC not exceeding 1500V, 2 Model Naming Principles
2.1 The naming of product models should be concise. 2.2 The full model of the product must represent a specific product and should not be confused or repeated. 2.3 The model of the product is composed of uppercase Chinese letters (hereinafter referred to as letters) and Arabic numerals (hereinafter referred to as numbers). 3 Product Model Naming
The full model of the product is composed of five parts: structural feature code, form feature code, variety feature code (including use code and design serial number), specification number and additional code. The specific composition is as follows
Note: Enterprises can name their own product models according to the characteristics of their own products, or adopt the naming method of product models and add the codes of different manufacturers as the special models of their own products. However, the model must be applied for by the enterprise and filed with the relevant industry unit to avoid confusion and duplication.
