FN-LB-I

Overvoltage suppressor (lightning-

protection barrier)

(red)

GND (green/yellow)

(black)

Composition

½" NPT thread

• 2-wire protection

• For insulated C&I circuits

• Fulfills requirements to 500 V

insulation to earth, housing

components and other intrinsically

safe circuits

• Installation directly in the hazardous

area for protecting the field devices

• Discharge current 10 kA

• Simple installation in the free cable

gland on the field device

• Uninterruptable operation (auto

reset)

By using an F*-LB-I, field devices and

control interface units are safely

protected from voltage surges due to

e. g. flash of lightning, switching

processes etc.).

This is accomplished by the derivation

of the higher current to ground and a

voltage limit during the high level pulse.

The continuous current capacity of the

circuit that is to be protected must not

exceed the rated operational current.
