Description

Type 1 and 2 protector according to UNE-EN 61643-11 and GUIDEBT- 23 of REBT. For equipment of Categories I, II, III and IV according to REBT. > Gas discharge tube inside. > Double connection in order to facilitate wiring (limited to 63 A). > Possibility of connection to a M5 fork terminal. > Suitable for TT systems. > Coordinable with other SPDs such as ATSUB and ATCOVER. > Quick response. > Withstands direct lightning strike current (10/350μs wave) of 100kA. > Limits supply following currents. > Thermodynamic control device with luminous alarm. > It has a test button to check the status of the protector. If the warning light illuminates in protective green in good condition. If not replace. > This indicator does not generate any operating current resulting from state control and does not increase leakage to ground during normal operation ATSHOCK series protectors have been tested in offi cial, independent laboratories obtaining their characteristics according to applicable standards (shown in the table). INSTALLATION ATSHOCK T25 surge protection devices are to be installed in parallel with the low voltage supply line, connected to a phase, neutral and ground. The power should be disconnected during the installation of the SPD. It can be installed in combination with ATSUB or ATCOVER. In either case, both must be separated by at least 10 meter cable or, if this is not possible, by a decoupling inductor ATLINK, in order to achieve a correct coordination between them. Classifi ed by IBERDROLA as protection against transient overvoltages Type 1 in Electricity Meter Room.
