The scope of this electrical installation handbook is to provide the designer and user of electrical plants with a quick reference, immediate-use working tool. This is not intended to be a theoretical document, nor a technical catalogue, but, in addition to the latter, aims to be of help in the correct definition of equipment, in numerous practical installation situations. The dimensioning of an electrical plant requires knowledge of different factors relating to, for example, installation utilities, the electrical conductors and other components; this knowledge leads the design engineer to consult numerous documents and technical catalogues | Electrical installation handbook Volume 1 3rd edition Protection and control devices 1SDC008001D0203 ABB SACE MW Electrical installation handbook Volume 1 Protection and control devices 3rd edition June 2005 First edition 2003 Second edition 2004 Third edition 2005 Published by ABB SACE via Baioni 35 -24123 Bergamo Italy All rights reserved Index Introduction.2 1 Standards 1.1 General aspects.3 1.2 IEC Standards for electrical installation.15 2 Protection and control devices 2.1 Circuit-breaker nameplates.22 2.2 Main definitions.25 2.3 Types of releases.28 3 General characteristics 3.1 Electrical characteristics of circuit breakers.38 3.2 Trip curves.49 3.3 Limitation curves.111 3.4 Specific let-through energy curves.142 3.5 Temperature derating.172 3.6 Altitude derating.187 3.7 Electrical characteristics of switch disconnectors.188 4 Protection coordination 4.1 Protection coordination.194 4.2 Discrimination tables.203 4.3 Back-up tables.228 4.4 Coordination tables between circuit breakers and switch disconnectors.232 5 Special applications 5.1 Direct current networks.236 5.2 Networks at particular frequencies 400 Hz and 16 2 3 Hz.247 5.3 1000 Vdc and 1000 Vac networks.264 5.4 Automatic Transfer Switches.276 6 Switchboards 6.1 Electrical switchboards.285 6.2 MNS switchboards.293 6.3 ArTu distribution switchboards.294 Annex A Protection against short-circuit effects inside low-voltage switchboards.297 Annex B Temperature rise evaluation according to IEC 60890.306 Annex C Application examples Advanced protection functions with PR123 P release.320 ABB SAGE - Protection and control devices
