ELXU1 surge protector is suitable for AC 220V / 380V, frequency 50/60Hz low voltage power system. It has overheated, overcurrent safety release function, response time less than 25ns, and the external dimensions are 41.1×45.2×75.8mm.
The ELXU1 surge protector is intended for use in low‑voltage AC power systems of 220 V/380 V at 50 Hz or 60 Hz, suitable for indoor installations such as floor distribution panels, computer rooms, and security monitoring centers. It offers B, C, and D level lightning protection with a flame‑retardant PA housing and built‑in over‑heat and over‑current safety release.
The manual lists technical parameters for various model variants (e.g., ELXU1‑20‑320, ELXU1‑40‑385), including maximum continuous operating voltage, discharge currents, voltage protection level, response time (<25 ns), and wiring capacity. Installation notes cover grounding requirements, wiring size, and optional remote‑signal alarm devices, while the ordering section explains how to specify model, voltage, current, and protection mode. This manual is written in Chinese.
| Maximum continuous operating voltage (UC) | 320‑420 V AC |
|---|---|
| Maximum discharge current Imax (8/20 µs) | 20‑65 kA |
| Rated discharge current In (8/20 µs) | 10‑30 kA |
| Voltage protection level (UP) | 1350‑2200 V |
| Response time | <25 ns |
| Connection wire capacity | 2.5‑35 mm² |
| Remote‑signal contact rating | AC 250 V/1 A, DC 250 V/0.2 A |
It is designed for AC 220 V/380 V systems with a frequency of 50 Hz or 60 Hz.
The device responds in less than 25 nanoseconds.
Grounding must be reliable, the conductor should be short, and the grounding lead length should not exceed 0.5 m.
