OBO FRD, FLD ac, dc signal line lightning protection device

Functions and applications: FRD, FLD, FRD2, and FLD2 is used for electronic measurement and control line of the protector, prevent the data line due to lightning or travelling wave caused by the surge overvoltage for related equipment damage. FRD and FLD series of protector is applied to not grounded (asymmetric, suspension) dual system. FRD can be installed in the allow resistance enlarged circuit, if the circuit is not allow resistance increases, the use of FLD. FRD2 and FLD2 series protector is used exclusively and related single system (symmetrical, voltage related). Here also have a series resistance and series inductance choice, if allow resistance increase is selected FRD2, for voltage control device is selected FLD2. Because they are designed for two level protection circuit, so it is also suitable for installation to LPZ1 - LPZ3. FRD and FLD of two stage circuit by gas discharge tube, pressure sensitive resistance and clamp diode composition, has the general flow, clamping time is very short and protection of the low level of characteristics. Installation: OBO FRD and FLD type protector can be installed in any standard switch box or distribution box, simply installed in 35 mm guide rail. No screw terminal reduces the cost of installation.

Performance schedule FRD, FLD protector use advantages

Installed on the 35 mm guide can be installed directly in the power distribution cabinet or switch box

But there is no problem to provide all kinds of voltage user oriented surge protection become possible

No screw pressure welding type terminal is easy to install

Y type circuit, safe for the line, neutral or protection ground to the surge can effectively restrain
