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
• Installation mode: fixed type, drawable type.
• Operation mode: motor operated,
manually operated(for serving)
• Pole number: three pole, four pole.
• Release type: intelligent type over-current controller,
under-votage instantaneous (or time-delay)
operation release: shunt release
