DS253E-690/WD

The DS253E-690/WD AC surge protector is designed for 3-phase 690VAC and mainly use for wind generator networks. The MOV technology allows a very low level of protection and an absence of following current. The DS253E-690/WD is mounted on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.

INSTALLATION

DS253E-690/WD Type 1+2 AC surge protector - 4 pole is 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).
