Elxu2 surge protector is suitable for ac 220v/380v, frequency 50/60hz low voltage power system, suitable for indoor use. The maximum continuous operating voltage is 385v or 420v, and the maximum discharge current can reach 80ka, 100ka or 120ka. The product has over-temperature, overcurrent safety release function, built-in visual alarm device, and can be equipped with remote alarm device (fs).
The ELXU2 surge protector is designed for indoor use in low‑voltage AC power systems (220 V/380 V, 50/60 Hz). It protects equipment in locations where large over‑voltages may occur by diverting surge currents safely.
Key features include a high discharge capacity up to 120 kA, flame‑retardant PA housing, overheat and overcurrent trip functions, dual‑trip safety design, optional remote‑signal (FS) alarm, and compliance with IEC61643‑1 and GB18802.1 standards (IP20). Installation is intended for LPZ0B‑LPZ1 zones or distribution panels, with strict grounding and spacing requirements. This manual is written in Chinese.
