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
• Selection of world-renowned components
• Large discharge current, fast response time
• Modular structure, composed of base and plug protection module, easy to install and maintain
• The module has overheating and overcurrent double tripping devices, failure display window, safe and reliable
• Multi-functional connection port, which can be connected to wires and busbars, and can be equipped with teleindication alarm terminals
• SPD complies with GB/T 18802.1/IEC61643-31 and GB/T50057-200 "Code for Lightning Protection Design of Buildings".
• SPD has protection modes such as phase-to-phase, phase-to-ground, neutral-to-neutral, neutral-to-ground and combination.
