Remote Signalling in option.
UL 94 V-0 Thermoplastic Housing.
IEC 61643-11 and EN 61643-11 compliance.
With the power status indication, indicating the working state of surge protector.
Application:
For protection of power supply systems.
For the protection of low voltage distribution systems against transient overvoltage caused by indirect lightning stroke and switching operations.
For using in the lightning protection zones concept at boundary 2-3.
Applied to power supply protection of equipment system in areas with high lightning risk.
Installation:
The line of surge arresters includes a full range of compact protectors for installation on DIN rail.
Green tab, normal work status, Red tab, failure status, need to be replaced rapidly.
Installation must be performed only by electrically skilled operator.
It can automatically protect the power network after proper installation.
In areas where storms are frequent, it is strongly recommended to install additional protection systems.
