Features:
DIN Rail Mounted Fitting, simple operation.
Type 2.
Flame retardant shell, fire proof, and safe to use.
Removable assembly, easy to plug and unplug.
Application:
BR275-40 series is designed and manufactured according to IEC61643-11 and GB18802.1 standards. The product has high lightning current discharge capacity, up to 40kA (8/20μs), which can prevent indirect lightning strikes and other surge current. This product can be mounted on a standard 35mm DIN rail mounting, it has high safety factor and long service life, it can be applied to single-phase power supply in the class II lightning protection of equipment and power system 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
