What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• Suitable for AC 50/60Hz
• Suitable for TT, IT, TN-S, TN-C and TN-C-S power supply systems with rated voltage 230/480V and below
• Suitable for the protection of low-voltage power grids and all kinds of electrical equipment and control systems
• Suppressing transient overvoltages exceeding the withstand surge voltage of the equipment
• Releasing surge energy and various surge overvoltages
• Standards compliant GB18802.1, GB18802.12 IEC61643-1, IEC61643-21 UL1449 ed.2
