Panelmatic is the preferred turnkey control panel designer, manufacturer, and integrator in North America. There is no job too big or small for us.

Our Protection Relay Panel Products include indoor and outdoor enclosures, custom fabricated, or off-the-shelf panels.

Some of our panels include:

  • Line panels
  • Distribution panels
  • Cap Bank Protection panels
  • RTU panels
  • Transformer protection panels
  • Bus differential panels
  • Annunciator panels
  • Feeder panels
  • Metering panels
  • Communication panels
  • SCADA/RTU panels

Power relay panels are essential for network operators, electricity suppliers, and other industrial enterprises in every sector., They protect electrical apparatus and transmission lines in the event of a short, overload, or any other fault. To achieve this function, they mostly utilize industrial control systems based on hardwired mechanical or solid state relays and timers.

The design and manufacture of these panels follows industry standards from the likes of NEMA, IEEE, ANSI, and NEC. However, there is also room for customizations to meet the needs of clients and project requirements. Some of these customizations may include:

  • Dedicated DC supply for each circuit and each protection. As well as DC supply supervision from the beginning to the end of the circuit.
  • Inter-compartment barriers and rear doors to suit the installation environment.
  • Ensuring compatibility with several relay brands, as well as integrated RTU and SCADA controls.
  • Fabricating the panel as a stand-alone, or integrating it into a power control center.

An important detail of power relay panels is its enclosure, which depends on its functionality, thermal consideration, and ingress protection. The functionality of the panel determines the number of components on it. So, the greater the functionality, the larger the panel and the enclosure.

A panel layout drawing should specify all dimensions to enable an appropriate enclosure design. As electricity passes through the components on the panel, significant heat generation occurs. This heat has to be kept below the level that the most fragile components within the enclosure can bear. Thermal considerations often influence material selection for components, and in some cases, bring about the need for a ventilation system or air conditioning.

For ingress protection, enclosures are categorized according to how impervious they are to the elements. North America primarily uses the NEMA rating whereas other areas of the world tend to specify IEC and IP ratings. The location of the panel (indoor or outdoor) and the type of particles (gas, liquid, solid) in its environment influence the enclosure rating selection.
