Un 400 V ATSUB-R 65 - 400 Max. discharge Line - ground voltage in kA nominal voltage Effective protection against transient overvoltages for electrical supply lines with or without neutral, using metal oxide varistors and gas discharge tubes. Protects three-phase TT, TNS, TNC and IT type lines. Medium protection according to the cascade protection recommended in the Spanish Low Voltage Regulations (REBT ITC23). 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 Q. 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. Tested and certified as a type 1, 2 and 3 protector according to the standard UNE-EN 61643-11 and GUIA-BT-23 from the REBT. Suitable for categories I, II, III and IV equipment according to the REBT. > Can be coordinated with other protectors such as ATSHOCK, ATSHIELD and ATCOVER series. > Made up of zinc oxide varistors and gas discharge tubes able to withstand very high currents. > It is possible to join the modules using rivets in order to obtain blocks of 2, 3 or 4 elements. > Short response time. > Does not produce deflagration. > Single-pole protection. > They do not cause any interruption to the power supply. > Small size modular protection. > Thermodynamic control device with mechanical warning and remote alarm. When the warning light is yellow, the protector is in good condition. If not, replace. ATSUB series protectors have been tested in official, independent laboratories, obtaining their characteristics according to relevant standards (listed in the table). It is possible to select a protector for the alternating voltage suitable for each particular case. For example, the technical datasheets of the optimal protectors for american voltages are also included (line voltage 230 V and line - neutral voltage 120 V), voltages greater than 230 V (line voltage 520 V and line - neutral voltage 300 V), and wind generators (line voltage 690 V and line - ground voltage 400 V). > INSTALLATION They are installed in parallel with the low voltage line, with connections to the phases that are to be protected and to ground. As an example, 3 ATSUB-R connections in a TNC type three-phase power supply line are shown. Installation should be carried out without power running through the line. When ATSUB protectors are installed as medium protection, they must be separated from the coarse and/or tight protectors 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. They are recommended for installations where large overvoltages can occur after the main switchboard and when these lines are not connected to very sensitive equipment.
