IA 25 230 is a voltage switching SPD with a single mode of protection, typically installed at the origin of the installation (e.g. in the Main Distribution Board (MDB)), in TN-systems or in TT-systems in combination with N-PE SPD model I 100, I 52 and with connection type CT2 (1+1 or 3+1), providing the following features and benefits:

Impulse test classification: Test class I and II / Type 1 and 2 (according to IEC/EN 61643-11);
• IA 25 230 is a self extinguishing, spark gap based switching SPD for the protection of low voltage installations against direct and indirect lightning effects;
• Impulse discharge current of 25 kA 10/350 μs;
• Nominal discharge current of 25 kA 8/20 μs;
• High self extinguishing capability of 16 kA rms (follow current interrupt rating);
Green LED Status Indicator;
• The special housing is designed for Pollution Degree 3.
