Abstract
The voltage surge protection device comprises at least one protection module designed to be connected to an electric switchgear apparatus. The protection module comprises at least one protective element for protection against voltage surges and separating means connected to at least one protective element to cause an electrical and/or mechanical separation representative of a fault of a protective element following an increase of temperature and/or electric current. The protection module comprises means for mechanical actuation connected to said separating means and comprising a mechanical control link. The electrical control link is placed in a tripped state representative of a fault of at least one protective element when said separating means have caused a separation.
