Low Voltage Surge Protective Device

ZOTUPLIMITER

L 2/10 230 230 ff 4 TT is a ready to install assembly of voltage limiting SPDs providing four modes of protection, typically installed in Sub Distribution Boards (SDBs) for three-phase plus neutral 230/400 V TT-systems downstream a RCD where connection type CT1 (4) is required according to HD 60364-5-534. This SPD is suitable for three-phase plus neutral
230/400 V TN-systems too, when high performances against TOV are required.
It provides the following features and benefits:

• Impulse test classification: Test class II according to IEC 61643-11 Ed. 1 (2011-03) and Type 2 according to
  EN 61643-11 (2012-10);
• Backup protection is not required with an upstream CB ≤ 160 A or up to an Isccr ≤ 5 kA rms;
• Three colour Status Indicator with progressive indication of remaining performance.

ZOTUPFILTER

ILF 4P 250/400 is a multimode SPD for direct and indirect lightning effects with integrated interference filter for high frequency disturbances, typically installed in in three phase plus neutral TN systems for the protection of Control Rooms, Data Centers or EDPs, with the following features and benefits:

• Impulse test classification: Test Class I, II and III according to IEC 61643-11 Ed.1 (2011-03) and Type T1, T2 and T3 according to
  EN 61643-11(2012-10);
• Although a special inductor ensures an effective attenuation of high frequency interferences capacity, it has an insignificant energy insertion loss if compared with the equivalent one of an insulation transformer.

ZOTUPACCESSORIES

CP 1 is an insulated extension clamp with 3 wire terminations and enables a V-connection even if the SPD
is not equipped with double clamps.

CP 1 can be assembled on the SPD's PE terminal as well as on phase or neutral terminals.

Data sheet CP

CP2 to CP8 are fork-type busbars with 2 up to 8 connection points. Typical application: to provide a common PE connection for
several SPDs. In TT system applications these busbars can also be used to provide a common neutral point connection to N-PE SPDs type I 12, I 52 and I 100.
