L 2/20 230 e
L 2/20 230 e is a pluggable execution, voltage limiting SPD, providing a single mode of protection, typically installed in Sub Distribution Boards (SDB), in TN-systems or in TT-systems in combination with N-PE SPD where connection type CT2 (1+1 or 3+1) is required. It provides the following features and benefits:
• Impulse test classification: Test class II / Type 2 (according to IEC/EN 61643-11);
• L 2/20 230 e is a voltage limiting SPD (varistor based) 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.
