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
• Voltage: The voltage continuously applied between the SPD terminals does not exceed the maximum continuous working voltage Uc
• The altitude should not exceed 2000m
• Ambient air chlorine temperature: normal range -5°C~+40°C, extreme range -40°C~+85°C.
• Relative humidity: should be between 30% and 90% at room temperature
• The SPD adopts 35mm standard guide rail to install the product in the distribution cabinet or box of the distribution box.
• The connecting line should be as short as possible, and the total length should be less than 0.5m
