The DS40 surge protectors are designed to be used in a multipolar configuration to protect single-phase, 3-phase or 3-phase+neutral AC networks, are used mainly for primary protection at the main electrical panel. They are sometimes associated with dedicated N/PE surge protector based on gas tube technology (DS40G).
2 possible configurations :
Common mode : CT1 configuration

DS40 surge protectors are connected between line(s), Neutral and protective wire (PE).

Example:

DS42-280 single-phase (L+N) protect

DS44-400 3-phase+N protect

DS44-230 3-phase+N protect

Common and Differential mode : CT2 configuration

DS40 surge protectors are connected between line(s) and Neutral to provide differential mode protection. A specific surge protector DS40G is connected between Neutral and Protective wire (PE) for common mode protection. This configuration provides the highest efficiency

Example:

DS44-400/G 3-phase+N protect

The DS40 impulse discharge capability classifies this SPD as regular Type 2, useful in case of medium lightning density areas. IEC60364 standard requests Type 2 SPD at the entrance of installation if the keraunic level Nk > 25.

This SPD is based on high energy varistor equipped with thermal disconnector and failure indicator, to comply with standards. Version with a remote signaling for disconnection indication is also available (DS4*S).
The DS40 is available for a large range of AC voltages. The DS40 is DIN rail compatible and is built with a plug-in module (DSM40-xxx) and a fixed base, which allows an easy and fast maintenance.

INSTALLATION

DS44-230 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).
