The DS250E is an extreme duty Type 1+2 designed to protect the entrance of the electrical installation. They are used to protect biphase, 3-phase or 3-phase + neutral networks in common mode or in common and differential mode. The 'Multi-Varistor' technology used allows the best possible behavior for the LV network (no follow-on current). The DS250E is mounted on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.
