IA 25 230 4 is a ready to install assembly of four voltage switching SPDs providing four modes of protection, typically installed at the origin of the installation (e.g. in the Main Distribution Board (MDB)) for three-phase plus neutral 230/400 V TN-systems with 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 4 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.
