PI-3k25

PI-3k is a three-phase surge arrester type 3, which is equipped with high-frequency filter, according to EN 61643-11 and IEC 61643-11. They are produced for rated load current within the range of 16, 25, 32, 50, 63, 80 and 120A for application use in TNS and TNC systems. éPI-3k range is designed for protection of three-phase electronic appliances in L.V. power supply systems against transient overvoltage and high-frequency disturbance. The function failure of varistors is indicated by target disconnection of mechanical thermal fuses which react to the varistors overheating above c. 120°C.

They can be manufactured in a comprehensive range of the Nominal voltages UN= 4, 48, 60, 80, 110, 120, 130, 160 and 230V (AC/DC).
