Die Gaskapsel Feinprotektoren aus der Serie 3403 von Huber+Suhner sind eine spezielle Gruppe von EMP-Ableitern, die besonders für Anwendungen mit geringer DC Spannungsversorgung über Koaxialkabel einen sehr hohen Schutz leisten.
Sie bieten eine extrem effektive Spannungsstoßreduzierung. Dies ermöglicht den Schutz selbst von besonders empfindlichen Mikroelektronikkomponenten, z.B. von permanent installierten GPS Systemen.
