DS70R type 2 AC surge protector

They are used mainly for primary protection of single and three-phase networks at the main electrical panel. They provide common-mode or differential-mode protection and are available in one-phase, single-phase, 3-phase and 3-phase+Neutral. This SPD is based on association of high energy varistors equipped with thermal disconnector and failure indicator, to comply with standards. The DS70R surge protectors are designed to be used in a multipolar configuration to protect single-phase, 3-phase or 3-phase+N AC networks. Each pole of the SPD is connected between Line(s) and PE and Neutral and PE.

Version with a remote signaling for disconnection indication is also available (DS7*RS).

The DS70R is available for the main values of AC voltages. The DS70R is DIN rail compatible and is built with a plug-in module (DSM70R-xxx) and a fixed base, which allows an easy and fast maintenance.

DS7xR-230 series:

DS71R-230: 230VAC surge protector - 1 pole used for 1 line: L or N
Combine two DS71R-230 to get DS72R-230 used for 230VAC single phase network (L+N), AC system: TN, protection mode: L/PE + N/PE
Combine four DS71R-230 to get DS74R-230 used for 230/400 VAC 3-phase network (3L+N), AC system: TNS, protection mode: L/PE + N/PE
Combine three DS71R-230 & one DS71G-600 to get DS74R-230/G used for 230/400 VAC 3-phase network (3L+N), AC system: TT-TNS, protection mode: L/N + N/PE

INSTALLATION

DS71R-230 Type 2 AC surge protector - 1 pole 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).
