ATSUB 65
- 65 : Max discharge current in kA
Tested and certified as Type 1, 2 and 3 according to regulations EN 61643-11 and GUIDE-BT-23 from REBT. Suitable for Categories I, II, III and IV equipment according to ITC-BT-23 from REBT.
- Coordinable with other SPDs 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 fix the modules through riverts in order to obtain blocks of 2, 3 or 4 elements.
- Short response time.
- Don’t produce deflagration.
- Single-pole protection.
- Their activation causes no interruption in power supply.
- Small size modular protection.
- Thermodynamic control device, mechanical warning and remote alarm.
When the warning is yellow the enclosure is in good shape. If not, replace.
AT82 Series SPDs have been tested in official and independent laboratories , obtaining their characteristics according to relevant standards (shown in the table).
There exists the possibility of selecting a protector for the working voltage in each particular case. In the technical datasheet, we have included as common examples the optimal SPDs for wind generators (voltage of 400V) and equipments using voltages common in the American continent (Voltage 120V)
Installation ATSUB
They are installed in parallel with the low voltage line, with connections to the phase that is to be protected and to ground. As an example we show the 3 ATSUB-R connections in a three-phase power supply line TNC.
The power should be disconnected during the installation of the SPD.
When ATSUB are installed as middle protection, they 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.
Their installation is recommended in places where important overvoltages can occur and when lines are connected to very sensitive equipment that can not withstand big overvoltages
