DAC80S-31-275

The new DAC80 range is defined by its high Imax parameter of 80 kA. Classified in Type 2, the products of this range are intended to be installed inside the main electrical panel. Its Imax setting of 80 kA makes the DAC80 recommended for installations located in areas susceptible to very strong lightning strikes. Thanks to its very high discharge capacity, this range will have a longer service life than conventional AC surge protection of Type 2 with Imax @ 40 kA. The electrical diagram of the DAC80 series consists of a block of two high-energy varistors combined with a single thermal disconnect system. CITEL is the only manufacturer to offer a complete range of products reaching such a high Imax. The products comply with EN 61643-11, IEC 61643-11 and UL1449 ed.5.

INSTALLATION

DAC80S-31-275 Type 2 AC surge protector - 3-phase+N are connected in parallel on the AC network and must be equipped with external fuses for short-circuit current protection

The total length of parallel connection wires to AC network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
Wiring is made by screw connections. On some models, a distribution bus can be used.
The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. Paralleling the protection wire with phases conductors must be avoided.
The cross sectional wire must be 6 mm² minimum for Type 2 SPD and 16 mm² for Type 1.
Local earthing resistance must be in compliance with the electrical rules.

Further information can be found in IEC 61643-12 standard (selection and application principles for low voltage SPD).
