IA 25 230 3+1 is a ready to install assembly of four voltage switching SPDs providing four modes of protection, typically installed in three-phase plus neutral 230/400 V TT-systems where connection type CT2 (3+1) is required according to HD 60364-5-534, with the following features and benefits:

Impulse test classification: Test class I and II / Type 1 and 2 (according to IEC/EN 61643-11 Ed. 1.0 2011-03);
• IA 25 230 3+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 100 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.
