Low Voltage Surge Protective Device

ZOTUPGAP

IA 25 230 1+1 is a ready to install assembly of two voltage switching SPDs providing two modes of protection, typically installed at the origin of the installation, e.g. in the Main Distribution Board (MDB), in single-phase 230 V TT-systems where connection type CT2 (1+1) is required according to HD 60364-5-534, with the following features and benefits:

• Impulse test classification: Test class I and II according to IEC 61643-11 Ed. 1 (2011-03) and Type 1 and 2 according to
  EN 61643-11 (2012-10);
• IA 25 230 1+1 is a self extinguishing spark gap and GDT based switching SPD, for the protection of low voltage installations against direct and indirect lightning effects;
• Impulse discharge current (L-N) of 25 kA 10/350 µs;
• Impulse discharge current (N-PE) of 52 kA 10/350 µs;
• High self extinguishing capability of 16 kA rms (follow current interrupt rating L-N);
• Green LED Status Indicator;
• The special housing is designed for "Pollution Degree 3".
