Product Description:
For installation at LPZ 0B-1 or higher, protecting low voltage equipment from surge. Specially designed for TT and TN-S system (“1+1” circuit). Designed according to GB 18802.1-2002/IEC 61643-1:1998-02.
Main character:
※ Small volume, high discharge capacity, pluggable
※ Quick response
※ Double thermal disconnection device , provide more reliable protection
※ Multifunctional terminals for connection of conductors and Bus Bar
※ Green window will change when fault occurs, also provide remote alarm terminal at the same time
