Function: F*-LBF-D1.32

F*-LBF-D1.32 are surge protection devices for fieldbus installations. They direct power surges to earth via gas discharge tubes, protecting field devices and control units from voltage surges and lightning strikes. They are in accordance with the fieldbus standard IEC 61158-2 and are certified Ex d (flameproof enclosure) for Zone 1.

FieldConnex ® surge protectors for field installation enable the coordinated use in a lightning protection zone concept in accordance with IEC 61312-1. Housings are available with 20 mm ISO or ½" NPT connecting threads for easy installation on outdoor junction boxes.
