Manufacture of control cabinets, MCCs and main LV switchboards

We integrate power, control and safety in every panel, ready to perform from day one.

Manufacture of control cabinets, MCCs and main LV switchboards

We design and manufacture industrial electrical panels that meet the highest technical and regulatory standards, with reliability, operational safety and energy efficiency.

  • Control cabinets
  • Motor Control Centres (MCCs)
  • Main Low-Voltage Switchboards

Advanced engineering for electrical panels

We use specialised software such as SIMARIS Suite (Siemens), ETAP and Caneco for:

  • Calculation of protection, voltage drop, selectivity and short circuit
  • Efficient and safe compartmentalisation design
  • Automated technical documentation to IEC 61439
  • Thermal optimisation, sizing and regulatory compliance

Control cabinets

PLC and safety cabinets designed, wired and tested in our workshop.

  • PLC and safety cabinets
  • Remote I/O, junction boxes and communications (Profinet, Profibus, industrial Ethernet)
  • Door-mounted HMI and control desks
  • EPLAN schematics and FAT in our workshop

Intelligent withdrawable MCCs

Withdrawable and isolatable units (SIVACON S8, SIMOCODE, SENTRON ECPD) for maximum availability.

  • Units can be withdrawn while the rest of the MCC stays in service
  • Communication with PLC, DCS and SCADA, ready for supervision with SICAM SCC
  • Predictive diagnostics
  • Internal arc protection (IEC 61641) and seismic certification

Main LV switchboards

Designed to IEC/UNE 61439 as the main power supply point of the installation.

  • Certified isolators, busbars and protection devices
  • Thermal and short-circuit studies
  • Energy metering and monitoring
  • Compartmentalised design and easy maintenance

Recent project: low-voltage switchboards for a CTG project

For a power station we took on the complete scope of the GCU and GTU low-voltage switchboards, from engineering to workshop testing:

  • Form 4b withdrawable switchboards up to 6,300 A
  • Design for short circuit, earthing and arc-proof performance
  • SIPROTEC protection relays with IEC 61850 (GOOSE) and Modbus
  • Manufacture, assembly and FAT in our workshop

Certifications and partnerships

  • Official Siemens and Schneider Electric partners
  • Approved solutions for critical industrial environments
  • Manufacture and design to international standards
  • Complete technical documentation and manufacturing traceability
