Annotation of standard text ČSN EN 60644-ed.2 (354722):

Tato norma platí primárně pro tavné vložky použité u motorů spouštěných přímým připojením na střídavou síť 50 Hz a 60 Hz. POZNÁMKA - Tato norma se může použít také pro motory s řízeným rozběhem, ale má se věnovat zvláštní pozornost výběru jmenovitého proudu tavné vložky (viz 8.1) a doporučuje se dohoda s výrobcem tavné vložky. Tavné vložky podle této normy mají odolávat normálním pracovním podmínkám a rázům při rozběhu motorů. Mají vyhovovat požadavkům IEC 60282-1. Účelem této normy je normalizovat ampérsekundové charakteristiky, uvést požadavky na zkoušení odolnosti proti rázům při rozběhu a dát návod na výběr tavných vložek určených pro použití s motory
