Abstract
An isolating device for a power semiconductor comprising n power terminals for a power grid comprises n module terminals, n grid terminals, n connecting lines which connect the module terminals and grid terminals and have overcurrent fuses, and a tripping controller. The tripping controller includes a detector for detecting the rupture of an overcurrent fuse and a tripping unit for tripping an overcurrent fuse. A power module contains a power semiconductor and an isolating device. A system installation contains at least two power modules connected in parallel. In a method for operating an isolating device, at least one of the overcurrent fuses is tripped upon a predetermined tripping criterion being met.
