L 2/20 230 e
Low Voltage Surge Protective Device
L 2/20 230 e is a pluggable execution, voltage limiting SPD, providing a single mode of protection, typically installed in Sub Distribution Boards (SDBs), in TN-systems. It provides the following features and benefits:
- Impulse test classification: Test class II according to IEC 61643-11 Ed. 1 (2011-03) and Type 2 according to
EN 61643-11 (2012-10);
- L 2/20 230 e is a voltage limiting varistor based SPD, for the protection of low voltage installations and equipment against indirect lightning effects;
- Short circuit current withstand of 50 kA rms with max. back-up fuse;
- NFC No Follow Current® technology, there are no follow currents drawn from the power supply system after operation.
