Electrical switchboards

Design, manufacturing and commissioning

We are experts in the design, development and commissioning of power and control electrical switchboards. With 30 years of experience, we have a workshop of more than 2,000 m² equipped for manufacturing excellence.

We make the installer's job easier with optimal, clean connections, reducing on-site labour costs. All switchboards include numbered terminal blocks, identification labels, compartmentation based on current rating, any form type up to 4B, switchboards rated up to 6,300 A, changeover for all generator sizes and a minimum 20% spare capacity provision.

30 years of experience in electrical switchboard design

Manufacturing

Our primary goal when designing a switchboard is to make the installer's job easier. We always seek the best solution with a fast response to quotation requests, and in most studies we propose several options so the client can choose the one that best fits their requirements.

  • Outputs terminated on numbered terminal blocks (up to 160 A)
  • Busbar connections for convenient wiring at higher ratings
  • Protection devices identified with custom labels
  • Standardised tightening torque
  • Minimum 20% spare capacity on all switchboards
  • Full traceability with order number per project
