Surge Protectors series D*-LBF-* serve as transient suppressors in the lines of electronic circuits. This approval applies to the following equipment: Base units Type DB-LBF-I1 and Type DB-LBF-I1.I and modules Type DP-LBF-I1.36.DE and TypeDP-LBF-I1.36.IE
Ambient temperature range: -50 °C to +50 °C for T6;-50 °C to +75 °C for T5;-50 °C to +80 °C for T4. The dielectric strength of at least 500 V of the intrinsically safe circuits of the Surge Protector seriesD*-LBF-* is limited only by the overvoltage protection. Terminals X5, X6, X7 and X8 are considered to be connected to earth. For use in type of protection Ex nA IIC T4...T6 Gc:The Surge Protector series D*-LBF-* shall be installed into an enclosure, which meets the requirements of a recognized type of protection, in accordance with IEC 60079-0.
