The use of  SCHRACK Vartec arresters is necessary in every consumer installation, which is newly built or significantly altered. In indoor mounting not dependent on position the national installation regulations must be followed (Austria: ÖVE/ÖNORM E 8001). Through their plug-in design, these arresters are very easy to replace in the case of an overload to an arrester.
