DC surge arresters of the DS220S DC, DS230S DC, DS240S DC type 2 series are intended for DC voltage protection and for photovoltaic devices. The surge arrester contains varistors with a thermal fuse. It is manufactured for nominal direct voltages of 12, 24, 48, 75, 95, 110, 130, 220, 280, 350 V DC.
Surge arresters include a thermal disconnector, optical fault indication and remote signaling of arrester status. Surge arresters are mounted on a DIN rail and have a modular structure - a basic part and exchangeable modules. The replaceable module enables easy and quick replacement of a damaged part.
