Automatic hybrid switching capacitor banks OPTIM HYB

Ultimate accuracy in compensation

Not all installations need the same type of compensation unit

The ever more unbalanced systems together with the implementation of new digital energy meters capable of registering individual inductive and capacitive reactive energy in each of the phases has forced us to reinvent power factor correction.

Traditional capacitor banks do not guarantee reactive energy elimination

The use of traditional compensation systems, which measure on a single phase and compensating with three-phase capacitors, cause system overcompensation or under-compensation, and register reactive values from the company energy meter while failing to guarantee the elimination of penalties on the customers' bills.

Thanks to hybrid compensation (with 3 current transformers), the new system patented by CIRCUTOR allows us to compensate any kind of consumption with a fast connection of single-phase capacitors between phase and neutral using thyristors. These capacitors are replaced with three-phase capacitors when the three-phase demand is stabilised, thus leaving the single-phase capacitors ready for new fast compensation needs and/or imbalances in the mains.

Reinventing power factor correction

Hybrid capacitor banks

The changing in the world of mechanical energy meters for multifunctional digital energy meters, capable of measuring reactive energy phase-to-phase, is forcing us to change the concept of power factor correction.

In this new scenario, to guarantee complete elimination of penalties for reactive energy on user electricity bills, CIRCUTOR has patented its OPTIM HYB hybrid capacitor banks, capable of measuring like the company power meter and compensating the reactive energy individually on each of the phases.

€0 guarantee


Three-phase measuring, the reply speed and the individual compensation by phase give us enough security to guarantee customers a €0 reactive item on their electricity bill.

* With correct unit selection and subject to CIRCUTOR's Guarantee Conditions.

Don't take risks with reactive energy

5 years warranty

Independently of the sector or the power consumed, today's electrical panorama means that we meet unbalanced loads in all kinds of installations.

CIRCUTOR's Optim HYB capacitor banks offer Exclusive Security with 0€* reactive energy penalties, and as we are confident about this, we give you a 5-year guarantee on the unit.

* With correct unit selection and subject to CIRCUTOR's Guarantee Conditions.

New CEM series of multifunction energy meters for DIN rail connection

In an increasingly globalized world is essential to manage efficiently the electrical consumption. In addition, the steady increase in the price of energy creates to the users the need to find new formulas to manage their installations.

The new CIRCUTOR’s CEM series of multifunction energy meters provides all the essential information about the different consumption habits of an installation, helping to save money, resources and improving the installation’s electrical energy efficiency.

The new CEM family range is composed by single and three phase direct or indirect static meters to measure the active energy with Class B/1 (EN 50470/IEC 62052-21) and reactive energy with Class2 (IEC 62053-23), all installed on DIN rail format.

In addition, a CEM-M module can be easily coupled to the system, providing RS-485 communications with Modbus protocol to the system.

New dynamic power controller with demand management

In recent years, CIRCUTOR has developed some of the most innovative and advanced solutions in the sector of photovoltaic self-consumption in Spain, leading initiatives and movements to facilitate the legalisation of installations interconnected to the grid for self-consumption with zero injection.

This has enabled CIRCUTOR to position itself as the company that offers the widest range of solutions in the Spanish market and with the most flexibility of control.

The range of CDP solutions from CIRCUTOR also enables a phase-by-phase control of the installations in order to take maximum advantage of the performance of the inverters. CIRCUTOR is reinforcing its commitment to offer solutions for photovoltaic self-consumption to the market, and is thus complementing its range of dynamic power controllers (CDP) by offering more options to manage the distributed generation of energy in the most efficient way.

As the icing on the cake to bring the year 2014 to a close, CIRCUTOR is launching the CDP-G on the market, the new Dynamic Power Controller with demand management. With this unit, a controlled injection to the grid can be guaranteed (or injection to the grid can be prevented, as in Spain's case). At the same time, maximum advantage can be taken of solar radiation surpluses for use in electrical consumption in installations.

The CDP-G incorporates all of the features of the CDP-0 and also includes new functions, making it a very flexible unit, in particular for use in the domestic and tertiary sector.

Some of the main features of the CDP-G are:

  • Capacity to control inverters from the leading brands
  • Use of surpluses of photovoltaic production
  • Monitoring via web (smartphone, tablet or PC)
  • Screen that shows consumption data, PV production, grid consumption and activation of manageable loads
  • Modbus/TCP communications for integration in SCADA

This makes it the ideal unit for optimising a photovoltaic energy installation for self-consumption in applications such as:

  • Managing heat pumps
  • Heating water with the use of thermal accumulators (swimming pools, homes)
  • Water pumping and irrigation applications
  • Production of compressed air

In this way, CIRCUTOR continues to be the leader in the sector of photovoltaic self-consumption with the most technologically advanced solutions on the market, thus offering better products to their customers.

The first step towards energy efficiency is no longer a matter of cost



Includes: EDS + CVM-NET4 + MC3

Control up to 4 different lines, (header, lighting, climate control, etc.) measure when, where and what you are consuming and reduce your consumption curve.

Includes: EDS + SMART III + TC *

Use the capacitor bank currently installed in your installation, replacing the current regulator with the Computer SMART III. This regulator has a built-in power analyzer which, connected to the EDS, can not only check the status of the capacitor bank, preventing penalties imposed due to reactive energy consumption, but also generate the general consumption curve of your installation.

* Choose 2 CT transformers with a ratio that matches that of the transformer installed in your installation.

Full range of Type B earth leakage protection and monitoring units

 CIRCUTOR extends the range for total earth leakage protection

All protection elements installed upstream must have the same or higher rating than those installed downstream, never lower, in order to guarantee the correct operation of the selective classification process. Therefore, if Type B is the maximum protection level of an element, a type A or AC unit cannot be installed downstream.

CIRCUTOR's range of Type B earth leakage protection units covers all the protection levels in your installation.

Why install Type B solutions?

Installing Type B earth leakage protection units ensures the safety of individuals and correct functioning for alternating current (AC), direct current (DC) or mixed current (AC/DC) intensities up to frequencies of 1 kHz.

Type A and AC earth leakage protection units do not detect smooth residual direct currents. Moreover, Type A units become more sensitive when a pulsating earth leakage current is accompanied by an smooth direct current. In these cases, protection is not as effective and compromises the expected safety levels.
