L 2/10 230 ff
Low Voltage Surge Protective Device
ZOTUPLIMITER
L 2/10 230 ff is a voltage limiting SPD providing a single mode of protection, typically installed in Sub Distribution Boards (SDBs), in TN-systems or in TT-systems in combination with N-PE SPD model I 52 or I 12 and where connection type CT2 (3+1 or 1+1) is required according to HD 60364-5-534. It provides the following features and benefits:
- L 2/10 230 ff is a voltage limiting SPD for the protection of low voltage installations and equipment against indirect lightning effects;
- Nominal discharge current of 10 kA 8/20 µs;
- Backup protection is not required with an upstream CB ≤ 160 A or up to an Isccr ≤ 5 kA rms;
- Short circuit current withstand up to 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;
- Three colour Status Indicator with progressive indication of remaining performance.
