Surge protection is a mandatory component in all commercial and private real estate according to DIN VDE 0100-443 und -534. The space-saving installation on the 40 mm rail system guarantees the best protection with the smallest space requirement.
The VARITECTOR ZPA S provides optimum protection against lightning and surge voltage damage in a width of only 36 mm. It combines type I, II, and III arresters in one unit and can be integrated without screws on three-phase busbars with separate PE connection. This also supports installations with 2 SLS switches. Product variants with two fused voltage taps enable the accommodation of additional applications. An optional signal output reports the protection status.
The VPU ZPA S is snapped on easily, quickly, and without tools in the pre-metering area. Tool-free installation increases safety and efficiency.
The pluggable additional tap with PUSH IN connection allows additional applications such as a modem to be connected directly – without extending the 40 mm busbar system.
Due to its overall width of only 36 mm, the ZPA S module can also be combined with 2 SLS switches and feed-in adapters. All requirements of VDE-AR-N 4100 are met.
Two integrated connectors for intelligent measurement integration saves time and components.
