Switchgear cabinet with a frame and door elements
摘要:
A switchgear cabinet with a frame and door elements. A side of the switchgear cabinet can be closed by an angle door element or by two superimposed door elements, a type of rabbet being optional, as a result of connection elements being mounted in pairs on vertical frame legs and aligned on a horizontal center plane in conjunction with suitably aligned closing and hinge elements.
