What should you look for in a switchboard enclosure?

Short answer

A switchboard enclosure has a dual function: as well as protecting the electrical equipment within, it must protect users from direct or indirect electric shock. It should therefore prevent the ingress of dust and water through a suitable ingress protection (IP) rating, offer suitable IK protection against impacts, and meet IEC Protection Class II standards. A modular setup that supports interconnectivity is also a common requirement, as it segregates the architecture and accommodates rapid expansion. We recommend our GTi ISO series of distribution boxes for low voltage switchgear, made from robust polycarbonate with interconnected housings that assemble quickly.

Enclosures for switchboards offer a dual function. In addition to protecting the electrical equipment within, as conventional solutions do, they should also protect users from any direct or indirect electric shock. They should therefore:

  • prevent the ingress of dust and water by means of a suitable ingress protection (IP) rating

  • offer suitable IK protection against impacts

  • ensure safety for operatives and the public by meeting IEC Protection Class II standards

On top of this, it is quite a common requirement for switchgear protective enclosures to be able to offer a modular setup that can support interconnectivity. This helps segregate the architecture, providing isolated protection. It is also a feature that end users appreciate highly, as it can accommodate rapid expansions or modifications.

To address these needs, we recommend our GTi ISO series of distribution boxes for low voltage switchgear. These are made of robust polycarbonate to protect against a number of environmental factors and climatic conditions. They are characterised by a modular design with interconnected housings that can be quickly assembled together, supporting maximum safety and scalability. They can also be prefabricated and integrated with short switch-off times, streamlining key projects.
