Surge Protection For AC Power Supplies FLT-SEC-H-T1-3C-440/25-FM

Plug-in lightning current arrester, in accordance with Type 1/Class I, with integrated surge-proof fuse, for 3-phase power supply networks with combined PE and N installed in one conductor (L1, L2, L3, PEN).


Nominal voltage UN : 400/690 V AC

3-phase TN-C, 400/690 V AC, Class I/II, 25 KA (10/350µs), with integrated surge-proof fuse

P/N : FLT-SEC-H-T1-3C-440/25-FM

- Integrated combination of spark gap without line follow current and surge-proof fuse.

- Can be used without separate backup fuse thanks to integrated overcurrent protection.

- Free of leakage current, suitable for use in the pre-meter area.
