Modular three-phase CTE, CTA, CTH, CTH/5 and three-phase CTM Type

The modular three-phase capacitors are designed to compensate indutrial networks in low voltage. Their installation and assembly is easy thanks to the modular design. Due to their construction within a burst proof sheet steel external case, this allows optium heat dissipation. Inside there are three single-phase units, which are equipped with pressure sentisitive disconnecvtors. In addiction to this construction, the self-extinguishing properties of the material used for the insulators and the protective cap represent a good safety-device against possible bursting.
