Surge Protective Device, Quick Response 100KA High Safety Voltage Surges Arrester Wide Application for Factory (3P 385V)

1. Surge Protection: When surge over voltage occurs in the system due to lightning stroke or other reasons, the protector will be quickly opened within nanoseconds, and the surge over voltage will be introduced to the ground to protecting the electrical equipment. 2. Reliable Working: With insulated terminals, the surge arrester ensures quick response and good bearing capacity for surge protection. 3. Clear in Display: Working status indication window, green indicates normal, red indicates fault, clearly showing the working status. 4. Premium Material: Adopting premium PC material that is flame retardant and very sturdy with , also very durable for long use. 5. Easy to Install: Comes with light weight and compact size as well, the 35mm electrical guide rail installation is simple to complete. Specification: Item Type: Surge Protective Device Model: SNYE 100 Colour: White Material: PC Maximum Discharge Current Imax: 100KA Nominal Discharge Current In: 60KA Protection Level Up: 2.5KV Protection Grade: IP20 Response Time: ? 25ns Maximum Wire Diameter: 35mm² hard wire or stranded wire. Recommended Connection: 4-25mm² Installation Method: 35mm electrical guide rail installation. Ambient Temperature: - 40?~+80? Main Structure and Working Principle: In three phase four wire system, three phase lines and one neutral wire are connected to the ground with protectors. Under normal conditions, the protector is in the state of high resistance. When the power grid suffers from surge over voltage due to lightning stroke or other reasons, the protector will immediately be turned on within nanoseconds, introducing the voltage over voltage to the ground, thus protecting the electrical equipment on the power grid. When the surge voltage passes through the protector and disappears, the protector will change to a high resistance state again, so as not to affect the normal operation of the power grid.
