SALTEK - SLP-440 V/3 - SPD - for low voltage

Pluggable module, visual fault signalling, module locking.

Three-pole varistor surge arrester.
Installation to LV installations, especially to sub-distribution boards in 400/690 V AC TN-C systems or TN-S without neutral conductor, eventually in IT system 400 V AC.
For protection of the installations and equipments against impact of induced overvoltages during a lightning strike or switching overvoltages.
