Commercial SPD Board
New Ready-To-Go Commercial SPD Board
There is now an increased focus on equipment protection against surge transient voltages. In commercial installations, regulations are much clearer about why and where a surge protection device (SPD) should be fitted, and state that it is the responsibility of the electrical designer to ensure the installation is compliant.
To support the market, we have developed a ‘ready-to-go’ solution to drive best practice installations thanks to the company’s new integrated commercial surge protection boards. It guarantees the best surge protection performance and helps to speed up installation on site.
What are the benefits of integrating surge protection device kits within the distribution panelboard?
Our commercial surge protection boards have been enhanced so that all surge protection kits can now fit within the distribution board - as opposed to being in a separate enclosure. This innovative solution provides the shortest connections to the surge protection device from the incoming supply. The solution is guaranteed to provide optimum surge protection performance and will help electrical contractors reduce installation times, satisfy compliance responsibilities, and remove the need to buy and install separate protection devices.
Are the Hager surge protection kits CT2 type arrangements?
Yes, our surge protection kits are included in commercial SPD boards are CT2 type arrangements. Our protection devices are applicable for all common UK earthing arrangements such as TN-C-S (PME), TN-S and TT earthing systems and remove the risk of incorrect selection. We have also introduced solid copper earth links in all commercial surge boards, achieving a best in class Up effective performance measured at the main busbars of the distribution board.
Do I need a secondary upstream protection device?
No. In the past, surge protection devices required an MCB/MCCB or fuses in the distribution board to provide backup protection using one of the outgoing ways in the distribution board. Our commercial board removes this requirement. For example, a four-way board retains the ability to be used for four TP ways rather than only three due to the SPD requiring one dedicated way. Removing the requirement for a secondary upstream device simplifies and speeds up installation timescales, meaning jobs can be completed more quickly.
What about surge protection kits for TPN boards? Our Type 1 SPDs have been extensively tested to ensure they work in conjunction with a Type 2 SPD in a downstream TPN board. With the IET Wiring Regulations advising that where multiple SPDs are installed, they should be coordinated to guarantee they work together; we have gone further with verified testing to ensure unrivalled performance.
