    Removable single-pole BT Type 2 surge protector - DS41-480

     

     

    Type 2 DS41 surge arresters are mainly used for the protection of single-phase and three-phase networks at TGBT. The electrical diagram includes a combination of high-power varistors equipped with disconnectors and their associated indicators: this assembly ensures a reinforced flow capacity. DS41 surge arresters are intended to be mounted in multipole to protect mono, tri or three-phase + Neutral networks, sometimes associated with a specific N/PE surge arrester.
