Questa Norma fornisce prescrizioni aggiuntive per i fusibili in alta tensione (HV) rispetto a quelle fornite dalla CEI EN 60077-2. Tratta i fusibili collegati a circuiti di alimentazione e/o ausiliari. La tensione nominale di questi circuiti è compresa tra 600 V c.c. e 3 000 V c.c. Questi fusibili possono essere utilizzati anche in circuiti c.a. ausiliari fino a una tensione nominale di 1 500 V. Questo documento, insieme alla
CEI EN 60077-2, descrive le caratteristiche dei fusibili, il funzionamento e comportamento nel normale servizio e, in caso di corto circuito, le proprietà dielettriche, le prove per la verifica di conformità, le informazioni per contrassegnare o da fornire con il fusibile.
Questa edizione costituisce una revisione tecnica e rispetto alla precedente, CEI EN 60077-5:2004-03 che rimane applicabile fino al 04-12-2022, è stato modificato il metodo di prova per la verifica della capacità di interruzione.
La presente Norma riporta la traduzione completa della EN IEC 60077-5; la versione inglese è riportata nel fascicolo 17481E di giugno 2020.

ICS

International Classification for Standards (ICS) is an international classification system for technical standards.

The ICS is a hierarchical classification organized on three levels.

Level 1 covers the main fields of activity in standardization, e.g. road vehicle engineering, agriculture, metallurgy.

Each field has a two-digit notation, e.g.

  43    Road Vehicle Engineering

The main fields are subdivided into groups (level 2). The notation of a group consists of the field notation and a three-digit group number, separated by a point, e.g.

  43.040    Road vehicle systems

Some groups are further divided into sub-groups (level 3). The notation of a sub-group consists of the group notation and a two-digit number, separated by a point, e.g.

  43.040.20 Lighting, signaling and warning devices

You can identify the ICS code of your interest by typing the code or a keywordword in the dropdown ICS field, and by selecting one of the filtered results.

Search also in the summary/description of the standard

By flagging this control, the search for keywords will not be limited to the Standard Number and Title fields, but will also be performed in the Abstract of the standard.

This way, you will get more results.

You should use this option when you can not find the desired result with the standard approach and it is necessary to extend the scope of the search: by increasing the number of results, you will increase the number of non-relevant elements, as well.
