ATBARRIER - FULL COORDINATED SURGE PROTECTION CABINET FOR POWER SUPPLY LINES

Correct overvoltage protection is only achieved if all of the protection stages are well coordinated. Otherwise, the most robust protection will not work, possibly even causing the destruction of the most sensitive protectors and even the equipment that they should protect.
For all of the protectors to work, they must be separated by at least 10 metres of cable or a decoupling inductor which also withstands the line operating current. The complete ATBARRIER systems have been designed in this way.
ATBARRIER series protection cabinets contain all the different protectors required for coordinated protection of all of the phases. ATBARRIER boxes are to be installed in series with the line. In normal conditions, they remain inactive without affecting line operation at all.
Compact box, easy to install and with the same advantages as Aplicaciones Tecnológicas protectors: robust, quick, reliable and tested according to applicable standards (IEC-EN 61643-11) in official and independent laboratories.

INSTALLATION

ATBARRIER surge protection devices must be installed in series with the low voltage power supply line.
Installation should be carried out without power in the line and can only be done by authorized professionals.

SAFETY AND MAINTENANCE

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 10Ω.
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.
