La presente Parte 331 della Norma EN 61643 si applica ai varistori ad ossido di metallo (MOV) .
Essa specifica le prove per i componenti utilizzati in applicazioni con tensioni fino a 1000 V in c.a. e 1500 V in c.c. su linee di alimentazione o di telecomunicazione o su circuiti di segnale; essi sono destinati a proteggere apparati o persone, o entrambi, contro le alte tensioni transitorie.
La presente Parte 331 si applica ai MOV con due elettrodi.
Essa non tratta i dispositivi ibridi e non si applica ai montaggi ed ai loro effetti sulle caratteristiche dei MOV; le caratteristiche fornite si applicano soltanto ai MOV montati esclusivamente nel modo descritto per le prove.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.
La presente Norma recepisce il testo originale inglese della Pubblicazione IEC e pertanto consta delle sole pagine dispari.
