SPD for low voltage, pluggable module, visual fault signalling, module locking, remote fault signalling
- combination of varistor surge arrester and encapsulated spark gap, connected in the 3+1 mode
- installation to LV installations, especially to sub-distribution boards in TT and also TN-S systems
- for protection of the installations and equipment against impact of induced overvoltage’s during a lightning strike or switching overvoltage’s
[SLP-275V/3S+1] 3+1 combined varistor and spark-gap arrester (Type 3); pluggable with visual and remote indication; suited to TT and TN-S systems.
