Uc = 460 V > AT-8399 ATSHOCK N: neutral-ground protection The highest protection against transient overvoltages for power supply lines at the point they enter the building. ATSHOCK series provide protection even against direct lightning strikes. Tested and certified with lightning impulse current 10/350 μs wave, 50 kA. Coarse protection according to scaled protection recommended in Low Voltage Regulation (REBT). Type 1 protector according to the standard EN 61643-11 and GUÍA-BT-23 from the REBT. For equipment of categories III and IV according to REBT. > > > > > Gas discharge tube inside. Suitable for TT, TN-C and TN-S systems. Can be coordinated with other SPDs such as ATSUB and ATCOVER. Quick response. Single-pole protection. Withstands direct lightning strike current (10/350 wave) up to 50 kA (ATSHOCK N up to 100 kA) > Fork connection with fork terminal included for 16 mm2 cable. > High energy diverting capacity. > Limits following current supply. > INSTALLATION ATSHOCK surge protection devices are to be installed in parallel with the low voltage supply line, connected to a phase and ground (ATSHOCK L) or to neutral and ground (ATSHOCK N). One ATSHOCK L is needed for each phase. Installation should be carried out without power running through the line. ATSHOCK can be installed in combination with ATSUB or ATCOVER protectors. In either case, both must be separated by at least 10 metres of cable or, if this is not possible, by an ATLINK decoupling inductor, in order to achieve correct coordination between them. Installation is recommended in distribution boards where the line enters the building and where direct lightning currents could penetrate. ATSHOCK series protectors have been tested in official, independent laboratories obtaining their characteristics according to applicable standards (shown in the table). Connection to earth is a must. Earthing in the whole installation must be bonded either directly or by a spark gap and resistance should be lower than 10 Ω. If the indications on this datasheet are not fulfilled during use or installation of the protectors, the protection provided by this device could be compromised.
