Reactive power compensation in ISO wall housing

Compensation system multicab-R-I

Reactive power compensation systems
multicab R ISO Wandgehaeuse

The multicab-R-I compensation system provides you with a high-quality and safe power factor correction system in an ISO wall-mounted housing. The specially manufactured ISO housing offers you protection against accidental contact with metallic components and therefore falls under protection class 2.

This power factor correction system is also suitable for all companies and production facilities where there is an increased level of contamination from dust, dirt particles or similar. The ISO design has a higher IP protection class and protects the power factor correction system more effectively against external contamination.
