SPD for Low Voltage L 25/100 230 t ff 3

Applications :

L25/100 230t ff3 is a voltage limiting SPD useful to protect low voltage applications against direct and indirect lightning strikes; Installation in Main Distribution Boards or at the origin of Low Voltage Systems

Technical Data :

Nominal AC Voltage : 230/400 V AC, Max Continuous Operating Voltage : 355 V AC/ 420 V DC, Number of Poles : 3

Impulse discharge current of 25 kA 10/350 μs; Nominal discharge current of 40 kA 8/20 μs;

It is a NFC No Follow Current® SPD because it prevents the circulation of grid follow up currents after operation;

Impluse test classification: class I test and II tests (according to IEC 61643-11 Ed. 1.0 2011 -03); Type ( acc.to CEI EN 61643-11 2012-10 ) : T1 e T2

Features :

Overcurrent protection is not required for Isccr ≤ 4,5 kA rms;

Three coloured levels Status indicator with progressive indication of performance.

The special case allows to match the Pollution Degree 3
