SPU is a combination of one-phase or three-phase MOV surge protection and power gas discharge tube connected in 1+1 or 3+1 circuits. SPU is surge arrester type 2 according to EN 61643-11. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 1-2 (according to IEC 1312-1 and EN 62305) for equipotential bonding and elimination of transient overvoltage that originate during atmospheric discharges or switching processes. Combined surge arrester SPU is suitable for use in TNS and TT systems. The main use of SPU arrester is in all kinds of industry, residential and administration buildings.They are to be placed into the secondary switchboards or into the control box.
