Pl-k50

PI-k50 is one-phase surge arrester type 3, according to EN 61643-11 ed. 2 and IEC 61643-11 and which is equipped with high-frequency filter. It is designed for applications in TN-S systems. PI-k150 is intended to protect one-phase electronic appliances in low voltage power supply systems against transient overvoltage and high-frequency disturbance. The varistors function failure is indicated by target disconnection of mechanical thermal fuses which react to the varistors overheating above c. 120°C.

While mounting PI-k50 surge arrester it is necessary to ensure that the ventilation holes in their housing are not covered. These arresters are to be placed as near to the protected appliance as possible, for example near to the electronic control systems of NC machines, electronics of robotic production and other sensitive electronic appliances. It is recommended to connect the protected appliance by appropriately dimensioned and shielded conductor. Position of applied HAKEL SPD can be horizontal, vertical, turned 90 and also 180 degrees and this does not affect SPD’s function or mentioned parameters. PI-k32, PI-k50, PI-k63, PI-k80, PI-k120 and PI-k150 are standardly manufactured with DS switching contact.
They can be manufactured in a comprehensive range of the Nominal voltages UN= 6, 12, 24, 48, 60, 80, 110, 120, 130, 160 a 230V (AC/DC).
