Drop resistant cup-arrester assembly

摘要

An arrester assembly for arresting over-voltage conditions in electric circuits and for isolating an arrester element from possibly harmful effects of external forces applied to the arrester assembly comprises a hollow cup and an arrester element located within the cup for arresting over-voltage conditions. A plastic sleeve is disposed within the cup surrounding the arrester element for isolating the arrester element from the possibly harmful effects of external forces applied to the assembly. A spring may also be provided within the cup for further isolating the arrester element from such effects.
