Surface treatment

The surface of the modular parts of the cabinet are treated with powder technology in RAL 7032 – grey, with a phosphate pre-treatment layer. The front and back frames are galvanized under paint. The instrument panel is made from galvanized sheet metal, the internal instrument bar and construction partitions are electroplated.

Description

The cabinet frame consists of front and back frame which are made from a special profiled welded material and four cross members screwed together to form one unit. The degree of required protection is ensured by the upper, rear and side covers (or also the bottom cover for IP 54) and the doors. The doors are closed using a three-point perch lock with a lift-bar-type door handle which can also be locked. The installed instruments can either be fixed to the instrument panel or to the horizontal rails that form the instrument frame along with vertical posts. Each cabinet is provided with suspension lugs (M16) to lift the cabinet using a crane. The cabinet dimensions are final, which means that none of the covers protrude from the frame profile. The switchboard frame is designed as a rigid product especially suitable for use in heavy-duty plants.
