摘要：The invention relates to a protection assembly including a protection module(20) that comprises at least one varistor (1) having an operation power threshold. A cutoffapparatus (21), connected to the protection module (20), includes a release mechanism(24), the means (33) for mechanically actuating said module being interconnected to therelease means (24) for opening contacts. The disconnection means comprises a thermaldisconnection means that includes: a first power threshold (S1) for disconnectingelectrical currents less than a first current level (11); a second power threshold (S2) fordisconnecting currents between a first and second intermediate current level (12A, 12B);and a third power threshold (S3) for disconnecting currents greater than a third currentlevel (13). The three disconnection thresholds are less than the operation powerthreshold.
