Selection SPDs & installation guidance

CITEL’s line of AC power surge protectors is designed to cover all possible configurations in low voltage installations. They are available in many versions, which differ in : Type or test class (1 , 2 or 3) Operating voltage (Uc) AC network configuration (Single/3-Phase) Discharge currents (Iimp, Imax, In) Protection level (Up)
Choosing Iimp : The impulse current Iimp is defined for Type 1 SPD. The minimum rating for Iimp is 12.5 kA by pole, following IEC 60364-5-534 . This level is adapted to the real phenomenon.
Coordination of Surge Protectors In order to provide maximum protection efficiency, it is necessary to create a «coordination» diagram, that means installation of a «primary » SPD at the network entrance and a «secondary» close to sensitive equipment.

This technology is the exclusive and patented technology of CITEL based on the use of specific types of Gas tubes: GSG. These components, the result of over 75 years of experience in the gas discharge tube field, have a behavior adapted to the power network and provide robustness and working stability: their association with varistors combines the advantages of both technologies.
The DAT Tester is a battery-operated tester to verify the correct operation of ESE Lightning Air Terminals. A high voltage is applied to the Air Terminal. Two test leads are used to connect the instrument and Air Terminal to be tested
