Reactive power compensation in the wall housing

Compensation system multicab-R-W

Reactive power compensation systems
multicab R 150 06 1122 07 SWSH

The multicab-R-W compensation system provides you with automatically controlled KBR power factor correction in the wall-mounted cabinet. Compared to the free-standing cabinet, the wall housing impresses with its more compact dimensions, making it compatible with almost any room size.

The compensation systems in the wall cabinet are manufactured individually for you and are technically designed for your specific application. This allows you to achieve reactive power compensation that is optimally tailored to your requirements. All compensation systems are available choked to prevent resonance damage and thus extend the service life of the capacitors. Unchoked systems are also available. KBR compensation systems are characterized above all by their quality and durability. We only use type-tested quality components in our handmade systems.
