Decoupling device

KNFBT series decoupling device is installed in a series of rated voltage 500V and below the low voltage

power supply system, used to increase the lead inductance, make up for the lack of wire length, the

coordination problem between the different specifications of surge protective device. Typical application

in surge protector of B level and C level are installed in a distribution box of the occasion. When the voltage

of the switch type lightning protection device and the voltage between the limited pressure type protector

line length is less than 10M, the limit between pressure type lightning arrester line length is less than 5M,

should install the decoupler between two level lightning protection device.

The decoupling device is connected in series in the circuit, the line should be according to the load current

to choose the corresponding decoupling device, (according to IEC61643-1 and GB50343 standards

for selecting)
