Modular protective housing e.g. for process engineering, has first and second potential rails coupled to form common potential rail

摘要

A modular protective housing includes a first housing module (101), which together with a second housing module can be inter-coupled for form a unified housing with a common volume in the coupled state. A first potential rail and a second potential rail are coupled so that the first potential rail and the second potential rail form in the coupled operating state, a common potential rail for the common volume. An independent claim is included for a field device with modular protective housing.
