SPD for Low Voltage L 3/30 230 ff 3

Applications :

L 3/30 230 ff 3 is a voltage limiting SPD useful to protect low voltage applications against indirect lightning strikes;Installations in Sub Disribution Boards 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 3 kA 10/350 μs; Nominal discharge current of 30 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 II test (according to IEC 61643-11 Ed. 1.0 2011 -03); Type ( acc.to CEI EN 61643-11 2012-10 ) : 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 (Conductive pollution or dry non conductive pollution that becomes conductive due to condensation occurs. To be found in industrial environment or construction sites (harsh environments).
