ELXU4-E surge protector is mainly used for AC 220V, frequency 50/60Hz low-voltage power system, suitable for indoor use. The product has the characteristics of small size, compact structure, large current capacity, repeated protection in a frequent lightning environment, fast response speed, TH35 type rail mounting, overheating, overcurrent safety release function, flame retardant PA shell, strong insulation strength, electronic release technology, and built-in visual light alarm device.
This manual describes the ELXU4-E surge protection device intended for use in low‑voltage AC 220 V, 50/60 Hz power systems. It explains the sources of over‑voltage, the protection modes, and the technical parameters such as maximum continuous operating voltage and discharge current.
The document also covers performance features, installation dimensions, wiring diagrams, and ordering procedures, including how to specify the required model and protection level when placing an order. This manual is written in Chinese.
| Maximum continuous operating voltage | 275 V – 385 V |
|---|---|
| Maximum discharge current | 10 kA – 20 kA |
The device can handle a maximum discharge current of either 10 kA or 20 kA depending on the model variant.
Specify the product name, quantity, model and protection mode, e.g., "1 x ELXU4-10E/320" for a 10 kA, 320 V unit.
