The "Surge protector" solution to protect and analyse your installations

The new SPDs DACN1-25CVGS are the designated successors to the existing DS250 and DUT250 series. As such, these Type 1 + 2+3 AC surge protectors feature a number of evolutionary improvements, such as the more compact housing, dual disconnect mechanism and remote signaling.

Typical applications

The new DACN1-25CVGS are designed for use on the AC side in critical infrastructures, large industrial installations and important installations for professional use which require closer monitoring and are very likely to be exposed to frequent overvoltages in order to avoid downtime or need to be monitored regularly/annually in accordance with IEC 62305-3, E7.

For example: hospitals and medical establishments, broadcasting and mobile communication networks, electricity suppliers, street cabinets, venues for major events/stadiums, industrial production sites, etc.

INSTALLATION

DACN1-25CVGS-31-275 Type 1+2+3 AC surge protector 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.
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.
