DAC1-13-31-275

Type 1+2 AC surge protector - 3-phase+N, 12.5kA / 50kA

DAC1-13 range are replacement product for DS13xR

The DAC1-13 series are extreme duty Type 1+2 pluggable SPD designed to protect AC powerline at the main switchboard of an installation equipped with lightning rod.

The technology ‘Multi-varistor” allows a very high discharge current capability in small dimensions and the best possible behavior to the AC network (no follow current).

Impulse current by pole (max. withstand 10/350µs by pole): 12.5 kA

Max. discharge current (max. withstand @ 8/20 µs by pole): 50 kA

In the light of their high discharge capability, the DAC1-13 surge protectors are especially compact and are available in multipolar versions to protect single or 3-phase AC networks.

This SPD is DIN rail compatible.

INSTALLATION

DAC1-13-31-275 Type 1+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).
