Our lightning protection products insist on using standard lightning protection chips that can withstand high lightning strikes. The unloading voltage is rapid.
Flame Retardant Material, Insulating Shell, Safe to Use.
Failure indication function, maintenance personnel can easily and quickly judge the quality of the product.
The Pluggable design can be replaced without interrupting the operation of the system. Press the contacts on both sides of the module to easily plug and unplug. Foolproof design, self-locking function, and easy maintenance.
Multiple choices, small size, and can also provide four-line products, which can be used as two second-line products to meet different installation environments.
