VARITECTOR PU ZPA S

Even smaller, even more powerful!

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 40mm 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.

Your benefits at a glance
