The modular surge protector for fieldbus consists of a base (DB …), and a plug-in module (DP-LBF-I1.36*) and is in accordance with IEC 61158-2. It directs power surges to earth via gas discharge tubes, protecting field devices. The device is certified intrinsically safe for circuits in hazardous area Zone 0 … 2/Div. 1 … 2, and for DART fieldbus. The surge protector is installed in Zone 1 … 2 or Div. 1 … 2. Choices support all concepts: interrupting/non-interrupting module exchange and direct/indirect grounding of the shield. The plug-in module can be exchanged without tools. The surge protectors support coordinated use in a lightning protection zone concept in accordance with IEC 61312-1. Installation in cabinets or junction boxes requires a minimum amount of wiring.
