This fieldbus surge protector is in accordance with IEC 61158-2 and mounts on the trunk connector of FieldConnex® High-Density and Compact Power Hubs, protecting them. It directs power surges to earth via gas discharge tubes. It is certified intrinsically safe for circuits in hazardous areas up to Zone 0/Div. 1 and DART fieldbus. The surge protector is installed in Zone 1 … 2 or Div. 1 … 2.

Integrated diagnostics (option) continuously monitor wear caused by surges. The end of the useful life and thus the need for exchange is indicated in two ways: via an LED and in the control room via the FieldConnex® Advanced Diagnostics software.

Installation on the trunk connector is without additional wiring even as retrofit. A single grounding bar connects surge protectors mounted side by side to a common grounding point.
