SZE3 system cabinets

Bolted framework of the cabinet
Closed-profile bolted design for high rigidity. Shape of the profiles ensures full symmetry of the cabinet frame, allowing doors and panels to be installed on either side plane. Each profile has a perforation with pitch of 25 mm on two planes, which makes the interior highly configurable. The material used gives increased corrosion resistance and simple galvanic connection of unpainted parts that are attached directly to the frame. In this way there is a possibility to avoid any additional ground connections. The perforation is designed for M6 self-tapping screws and special M8 cage nuts. The perforation modular arrangement in the cabinet frame is compliant with the EN 60917 standard.

Door
Door is made of steel sheet powder coated in RAL 7035. The door can be mounted to the frame at any plane, on four hinges with an opening angle of 150°. With its symmetric design, the door can be mounted for either left or right handing. The door comes with 25 mm perforated stiffening frame as standard. The door has a four-point rod lock as standard. Cabinets with widths of 1000 mm and 1200 mm have a double door; cabinets with widths of 800 and 600 mm have a single leaf door. On request, we can deliver glazed and/or ventilated door.

Rear panel and side panels
Simple and quick installation with screws. Due to the frame symmetry, for cabinets of the same width and depth they may be used interchangeably. Rear and side panels are made of steel sheet powder-coated in standard RAL 7035. They have M8 earthing bolts as standard.

Top panel
Steel panel, powder painted in RAL 7035, with a sealing gasket. Serves as the top plate. Comes as a solid version and a version with a 380x380 or 380x210 mm opening (for blanking plate or fan unit).

Bottom plate
Perforated plate with 3 sliding blanking plates (the same as in SZE2 cabinet). The blanking plates are fixed with special cut-in screws that ensure continuity of equipotential bonding (earthing). Bottom plate and the blanking plates can be removed to achieve a cable grommet virtually as large as the cabinet base.

Mounting plate
The cabinet is fitted with a galvanized mounting plate with a thickness of 3 mm as standard. It can be mounted at any depth of the cabinet. What's important, the mounting plate can be installed as far as the cabinet's back between the rear posts of the frame, all the mounting space in the cabinet can be used completely. The mounting plate is fitted with guides for easy installation in the cabinet, as standard.

Earthing
All the necessary elements have M8 bolts for earthing them to anywhere in the cabinet frame.

Compatible with third-party installation systems
The SZE3 cabinet framework allows the use of the Lütze LSC Wiring System.
