Fixed capacitors' batteries

Fixed capacitors' batteries for reactive energy compensation:

CTA, CTE and CTM capacitors are perfect for compensating loads. The modular three-phase capacitors are designed to compensate industrial networks in low voltage. Their modular design simplify their installation and assembly. The external case is made of a burst proof sheet steel which allows optimum heat dissipation. Inside, there are three single-phase units, which are equipped with pressure sensitive disconnectors.
