The YC1.5W-0.28 series is a specialized line of Low Voltage (LV) Surge Arresters engineered to protect electrical equipment from the damaging effects of transient overvoltages. Utilizing high-quality Zinc Oxide (ZnO) varistors, these arresters offer excellent non-linear V-A characteristics and rapid response times. The red silicone rubber housing provides exceptional hydrophobic properties and resistance to environmental degradation, making them ideal for both indoor and outdoor low-voltage distribution applications.
Technical Features:
Optimized Protection: Designed specifically for 280V (0.28kV) systems, ensuring a low residual voltage to protect sensitive downstream components.
Durable Construction: The polymer housing offers superior creepage distance and anti-tracking performance compared to traditional porcelain.
Reliable Performance: Fully compliant with IEC 60099-4 standards for metal-oxide surge arresters without gaps.
Compact Design: The YC series features a space-saving geometry, perfect for installation in tight distribution boards or integrated into low-voltage transformer bushings.
