Foreword
GB /Z 25842 "low-voltage switchgear and control equipment over-current protection electrical" is divided into two parts.
--- Part 1. The application of short-circuit fixed;
--- Part 2. Over-current conditions of selectivity.
This section GB /Z 25842 Part 1.
This section identical with IEC /T R61912-1.2007 "Low-voltage switchgear and control equipment over-current protection Part 1.
Short-circuit quota application "(in English). For ease of use, this section made the following editorial changes.
--- Remove the foreword of the international standard;
--- "This report" to "this section";
--- "List of 3 definitions and characteristics in alphabetical order" should read "3 Definitions and characteristics index".

Introduction
GB 14048 and GB 7251 are currently on the electrical switch and complete sets of equipment were provided for the short-circuit quota, the quota according to equipment in a peak
The value current level, the current rms for a specified time and/or a current level dependent on the series connected short-circuit protection
Depending on ability. In fact circuit designers need to fully understand the various short-circuit quota and can be properly applied to avoid the circuit or device
Improper short-circuit protection while maximizing equipment and system capacity to avoid additional waste.
Low-voltage switchgear and control equipment
Over-current protection appliances
Part 1. Application of short-circuit quotas
1 Scope
This part of GB /Z 25842 as a low-voltage switchgear and control equipment and complete sets of equipment standard short-circuit the application guidelines, summarized
The definition of short-circuit quotas, and its application to provide the corresponding examples.
Note. This section does not itself involve the installation of household appliances.
