Railway applications - Electric equipment for rolling stock - Part 4: Electrotechnical components - Rules for AC circuit-breakers
IEC 60077-4:2019 gives rules for AC circuit-breakers, the main contacts of which are connected to AC overhead contact lines; the nominal voltage of these circuits being in accordance with IEC 60850. This document, together with IEC 60077-2, states specifically:
a) the characteristics of the circuit-breakers;
b) the service conditions with which circuit-breakers comply with reference to:
- operation and behaviour in normal service;
- operation and behaviour in short-circuit;
- dielectric properties;
c) the tests for confirming the compliance of the components with the characteristics under the service conditions and the methods to be adopted for these tests
d). the information to be marked on, or given with the circuit-breaker.
This second edition cancels and replaces the first edition, issued in 2003. This edition includes the following main technical changes with regard to the previous edition:
a) standard values of transient recovery voltages and test procedure are reviewed;
b) procedure of verification of temperature rise is changed;
c) air-tightness test as type test, insulation resistance measurement are added
Applications ferroviaires - Equipements électriques du matériel roulant - Partie 4: Composants électrotechniques - Règles pour disjoncteurs à courant monophasé
L' IEC 60077-4:2019 donne les règles relatives aux disjoncteurs à courant monophasé dont les contacts principaux sont destinés à être raccordés à des lignes aériennes de contact à courant monophasé. La tension nominale de ces circuits est conforme à l'IEC 60850. En complément de l'IEC 60077-2, le présent document précise particulièrement:
a) les caractéristiques des disjoncteurs;
b) les conditions de service que les disjoncteurs supportent du point de vue:
- du fonctionnement et du comportement en service normal;
- du fonctionnement et du comportement en cas de court-circuit;
- des propriétés diélectriques;
c) les essais de conformité des composants avec les caractéristiques dans les conditions de service ainsi que les méthodes d'essai correspondantes à utiliser;
d) les informations à donner ou à marquer sur le disjoncteur.
Cette deuxième édition annule et remplace la première édition, parue en 2003. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les valeurs normalisées des tensions transitoires de rétablissement et la procédure d'essai sont revues;
b) modification de la procédure de vérification de l'échauffement;
c) ajout de l'essai d'étanchéité comme essai de type et du mesurage de la résistance d'isolement.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee
