Features / performance
Components
CLZ capacitor (460 V) Contactors with pre-insertion block and quick discharge resistor Two-pole protection circuit-breaker for capacitor bank and regulator operations. Power factor regulator of the computer Max series. Detuned filters tuned at 189 Hz (50 Hz) /227 Hz (60 Hz) for the protection against harmonics present in the network and to avoid the problems of resonance with fifth or higher order harmonics. Built-in thermostat for the disconnection of the step in case of excessive temperatures (90 ºC). Auto-transformer.
Optional
Manual capacitor bank header switch Automatic capacitor bank header switch Automatic switch + Earth leakage protection at the capacitor bank’s header Forced ventilation unit + thermostat Polycarbonate plate to protect against direct contacts
