Reliable Working: Equipped with insulated terminals for quick response and robust surge protection capacity, ensuring reliable performance. Clear Display: Features a working status indication window with green for normal operation and red for faults, providing clear visual status updates. Premium Material: Constructed with premium flame-retardant PC material for durability, sturdiness, and corrosion resistance, ensuring long-lasting use. Easy Installation: Lightweight and compact, facilitates simple 35mm electrical guide rail installation for quick and hassle-free setup. 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.
