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
• Themosetting material shell, high stability of Mechanical property and size, Excellent corrosion resistance, and Heat resistance and arc resistance.
• Beautiful appearance, exquisite results, quick tripping, din rail mounting.
• Breaking capacity up to 10000A.
• Optimal design for contact system and trip mechanism.
• Special arc-extinguishing design, More perfect.
• High reliability and long use life.
