Product DescriptionGD-B series surge protector device(in
short:SPD,alias:surge protector,surge arrester) is suitable for
TN-S, TN-C-S, TT, IT etc. Power supply system of AC 50/60Hz,≤380V,
ans installed on the joint of LPZOA zone or LPZOB and LPZ1 zone,
which protects the electric network not shocked by the thunder,
it's designed according to GB18802.1, IEC61643-1, it adopts 35mm
standard rail, there is a failure release mounted on the module of
surge protective device, when the SPD fails in breakdown for
over-heat and over-current, the failure release will help electric
device separate from the power system and give the indication
signal,green means normal,red means abnormal, it's also could be
replaced for module when has operating voltage.Intensity of Remote
Signalling Alarm ContactFailure indication and centralized remote
signalling alarm dry contacts;High discharge capacity and low
residual voltage;Over-temperature protection;IP20, UL94
V0 Product Features GD-B series surge protective devices
is suitable for B grade lightning proof, installed on the joint
of LPZOA zone or LPZOB and LPZ1 zone, which protects the
electric network not shocked by the thunder or surge over voltage.
GDB-100,GDB-80,GDB-60 are usually in installed in low voltage
main distribution box connected to the incoming end of the
buliding. Product Parameters ModelGD-BRated Operating
