MODULE FOR PROTECTING AGAINST OVERVOLTAGE AND PROTECTION ASSEMBLY INCLUDING SUCH A MODULE

摘要

The invention relates to a module (20) for protecting against overvoltage, comprising at least one varistor (1) mechanically connected to driving means (10) by a first thermal separator (P1). The melting of the first separator (P1) enables the movement of the driving means (10). The first thermal separator (P1) has a first melting time constant s1 and a first melting temperature T1. The varistor (1) is mechanically connected to the driving means (10) by a second thermal separator (P2), and the melting of the second separator (P2) enables the movement of the mobile driving means (10). The second thermal separator (10) has a second melting time constant s2 and a second melting temperature T2, the second temperature T2 being higher than the first temperature T1, and the first time constant s1 being higher than the second time constant s2.
