Product Features

E-Cube Energy through its trusted partners offers factory built HT Metal Enclosed Capacitor Banks that offers the ultimate ease of installation and help reduces kVA billing and power factor penalties also improves voltage profile and increases power flow capability through the network. These panels can be equipped with various protection relays, meters, and sensors to protect the capacitor bank as well as the system from over-voltage, out-of-balance operation from capacitor failure,internal faults, and over-temperature due to fan failure. Protection devices are integrated with the control system and other components to form a fully integrated system.

In addition various configurations are possible based on the application as listed below:

Fixed Bank: Qc/Sn < 15% the reactive power of the capacitor banks is constant and they are started up or shut down when a predetermined KVAr value is reached. It is an “on/off” type of operation.

Automatic Bank: Qc/Sn > 15% the customer specifies automatic start up or shut down for the capacitor bank (controlled by relay). The reactive power of the capacitor bank is split into “steps” with the possibility of starting or stopping more or fewer steps. The reactive power corresponds to the change in load requirements.

Harmonic Filtering Bank: Harmonics are an important aspect when considering power factor correction. The range includes a number of options to overcome these harmonics. Harmonics are not only found in industrial networks,they can also spread into the distribution network and cause problems for other power users.


  • Ensures highest PF on a continuous basis thereby ensuring the maximum possible PF rebates and reduced energy bills
