CIRCUTOR: Electrical metering, power quality and energy management equipment

CIRCUTOR supplies electrical meters, power analyzers and collection software for energy monitoring in buildings and industrial installations.

Best for: Comparing current-sensor and communication options for a panel or feeder monitoring project.
Less suited to: Buying a meter by family name without matching the current input and network interface.
Deployment: DIN-rail and panel instruments connected to local monitoring or energy-management systems.
Data in: Current transformers, low-current sensors or Rogowski coils, depending on the meter variant.
Pricing: Pricing was not established from the reviewed technical sources; request a quote for the exact configuration.

Overview

CIRCUTOR combines electrical measurement hardware with equipment for improving electrical efficiency. Its company overview covers metering, power quality, electrical protection and renewable energy applications. For someone assembling an energy-monitoring system, the useful starting point is the meter's installation and electrical input rather than the entire product catalogue.

The CVM-E3-MINI range illustrates the available choices. It fits a three-phase analyzer into a DIN-rail enclosure, with distinct versions for conventional current transformers, low-current sensors and flexible Rogowski coils. Serial and network versions serve different collection architectures. These options help match a new installation or retrofit to the wiring space and communication infrastructure already available.

Offering

The CVM-E3-MINI catalogue names three important current-input options. ITF-WiEth takes 1 A or 5 A transformer secondaries, MC-WiEth takes 250 mA sensors, and FLEX-WiEth uses Rogowski sensors. All three listed WiEth variants provide Ethernet and Wi-Fi with Modbus TCP. The serial FLEX-485-IC version instead lists RS485, Modbus RTU and BACnet.

These are physical purchasing decisions as well as software decisions. A sensor already fitted around a conductor has to match the meter input. The listed serial versions also include a digital input and transistor output, whereas the WiEth listings emphasize network access. The company catalogue provides exact references for ordering each configuration rather than treating them as software-selectable modes of one universal instrument.

Products and platforms

PowerStudio
Energy-management software

Current and legacy releases have device-generation compatibility boundaries.⁶

Technology

The WiEth application article describes Ethernet and Wi-Fi for communicating measurements to an energy-management system. Bluetooth has a different role: configuring network parameters through the MyConfig application. A Bluetooth-capable setup process therefore does not imply that the meter continuously exports readings over Bluetooth.

CIRCUTOR also describes configuration through a local web interface or the instrument display. Its commissioning guidance discusses matching each voltage phase to the corresponding current sensor and checking transformer direction. Incorrect pairing changes power, power factor and energy results even when communications are working. These checks are particularly useful when comparing a successful protocol read with a trustworthy electrical measurement.

Markets

CIRCUTOR's software and firmware library separates current PowerStudio releases from legacy versions and publishes device-specific update packages. It explicitly identifies last-compatible legacy releases for some EDS, MDC-20 and CVM product families. An existing site's software version and instrument generation therefore matter when planning an extension.

The broader download library includes product manuals, catalogues, firmware and protocol material, including QNA 600 IEC 61850 files. This makes the company relevant both to ordinary consumption monitoring and to more specialized power-quality projects. Those uses call for different instruments: selecting a compact consumption analyzer should not automatically be treated as selecting the required power-quality recorder or substation interface.

Company

CIRCUTOR dates its origins to 1973 in its anniversary history, describing a business formed around more efficient use of electricity. Its current company page identifies the headquarters in Viladecavalls, near Barcelona, Spain, and organizes the business around measurement, protection, compensation, renewable energy and software.

The historical material explains why its offer spans both collecting energy information and changing the electrical installation itself. Metering products sit alongside power-factor correction and harmonic filtering equipment. Buyers can use the company's technical download and support channels to narrow that broad portfolio to a measurement task, installation arrangement and exact communication variant before requesting a quotation or choosing a replacement.
