Not included in 770 mm high enclosures without reactors, in version with circuit breaker with power ≤ 125 kVAr, in version
without circuit breaker with power ≤ 150 kVAr.
(4)
Enclosure with detuned reactor, check the frequency is compatible with your electricity supplier. For other frequencies, please
consult your Legrand Group representative.
(5)
Above this harmonic level, please contact your Legrand Group representative who can do an audit of the installation and offer
you a bespoke solution to meet your requirements (compensation, harmonic processing).
