Surge Protection For AC Power Supplies VAL-MS-T1/T2 335/12.5/3+1

Universal varistor-based plug-in lightning/surge arrester for 3-phase power supply networks with separate N and PE (5-conductor system: L1, L2, L3, N, PE), for Lightning Protection Levels III and IV.


Nominal voltage UN :  240/415 V AC

3-phase TN-S, 240/415 V AC, Class I/II, 12.5 KA (10/350µs)

P/N : VAL-MS-T1/T2 335/12.5/3+1 

- Plugs can be checked with CHECKMASTER.

- Secure hold of plugs in the event of high lightning current loads and strong vibrations thanks to new latching.

- Optical, mechanical status indication for the individual arresters.
