Features:
The technical performance of the products meets the standard technical equipment of GB18802.1 and IEC61643-11.
It adopts 35mm standard rail.
This model designed in modular with excellent airtight property.
It is with 35mm din rail, which make it easy for installation.
Application:
Installation at LPZ 0 -1 or higher, protecting low voltage equipment.
Applied in PSD Class I+II (Class B+C).
Connected to AC low-voltage power systems for protection of equipment from transient over-voltage caused by the inducted lightning stroke or internal power systems.
Installation:
The protector is installed with standard 35mm track.
The protector is connected by 4 ~ 35mm copper wire.
No need to adjust after the protector is installed as required.
During operation, regularly check whether the module is red; replace the failed component in time.
