DAC15CS-20-275

The DAC15C Type 2 or Type 3 Compact plugable surge protectors (SPD) are intended to be connected at the TGBT or divisional panel level. Their compact format allows them to be installed in very small spaces. The DAC15C SPDs are available have a discharge capacity of 15 kA, in single-phase or 3-phase configuration and with various voltages in order to protect any type of networks. Based on varistance technology equipped with disconnector and associated indicator, these SPD ensure maximum protection efficiency, flow capacity and reliability.

INSTALLATION

DAC15CS-20-275 Type 2/3 AC surge protector - single-phase 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).
