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.
