PFC - Power Factor Correction

Terasaki is the exclusive UK distributor of a complete range of products and systems for low, medium and high voltage power factor correction. If you are outside the UK Contact us for details of local suppliers.

We have a huge range of affordable modular cassettes for switchboard installation and prefabricated freestanding capacitor banks.

We hold a full stock of modular cassettes which we can despatch next day.

Loose Power Factor Correction

Terasaki/Enerlux three phase PRT capacitors are self-healing and consist of three single-phase elements made of metalised polypropylene film with a delta connection in a cylindrical casing of extruded aluminum. The fixing spigot is M12 x 12 mm and is used to earth the capacitor.

The capacitor is enclosed with a steel disc on the aluminum casing, ensuring a perfect air and water seal. The capacitors are designed with an overpressure disconnecting safety device. This protection immediately cuts off the power supply to the capacitor in the event of a fault due to excessive overvoltage. A fiberglass reinforced mount supports the three connection terminals. We recommend you leave at least 25 mm clear space above the connection terminals to allow the overpressure device to work properly.

All capacitors are manufactured to the highest standard (IEC 60834-1/2) ensuring excellent duty and performance.

Easy Installation of Power Factor Correction equipment

Wall-mounted and free-standing units allow simple addition of power factor correction to an existing system.

Standard modular cassettes for switchboard installation.

Easy to install with busbar or cable connections available

Our new small cassettes have been designed to be installed extremely easily. The units offer a 70% reduction in width compared with standard PFC modules. This will minimizing the switchboard size, and save costs.

Automatic power factor regulator with up to 6 or 12 steps.

Regulator models ECEPF 8T and ECEPF 12T monitor the temperature of the PFC units and have automatic cut out facilities.
