IA 25 230 4
Low Voltage Surge Protective Device
ZOTUPGAP
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-S systems 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 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".
