Abstract

A switchgear cabinet monitoring arrangement with a control device for monitoring switchgear cabinet functions, including a door position, and for generating monitoring signals for signaling to and/or controlling components relating to the switchgear cabinet functions and installed in the switchgear cabinet or on the switchgear cabinet. A simple and compact design is achieved because the control device is limited to monitoring preselectable threshold values, a door position switch is installed on or in the device housing, and the device housing has one or several indicator elements which react with a visual or acoustic indication when at least one threshold value is upwardly or downwardly exceeded.
