Classic - non blocked

Classic (unprotected) compensating switchboards with the power of tens to thousands of kvar are suitable, where the degree of network affection by non-linear appliances - sources of harmonics - is low and where its material increase is not assumed in the nearest future.

Workmanship: wall mounting for lower powers up to 100 kvar, outdoor mast mounting, classic indoor with cable lead from below or from above and/or by bus bars, without protection (outlet switched off and protected in the main switchboard) or protected in the switchboard by a fuse switch-disconnector or circuit breaker.
