The DS500E range of surge protectors are Type 1 + 2, very high power, they are intended to be installed at the entry of the Low Voltage installation. They are used to protect single-phase, three-phase or three-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 DS500E range is installed on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.
