Mounting kit Rittal 3073.000 — Grey thermoplastic polyester (PBT) with fiberglass

Rittal 3073.000 is a mounting kit manufactured from grey thermoplastic polyester (PBT) reinforced with fiberglass. It is intended to provide reliable mechanical support and secure fixing for busbar and related components inside enclosures and control cabinets. The material combination ensures resistance to common industrial chemicals and good dimensional stability under typical electrical installation conditions, while the kit geometry is designed to fit three-pole busbar arrangements with a 100 mm bar centre distance and busbar widths between 30–60 mm and thickness up to 10 mm.

Advantages

The mounting kit offers a balanced combination of mechanical strength and electrical insulation due to PBT reinforced with fiberglass. Its grey color and compact design enable neat integration into cabinets and switchgear. The component resists wear, provides stable mounting for busbars at a 100 mm centre distance and reduces the need for frequent replacement in standard industrial environments. Installation is compatible with common panel layouts and supports three-pole busbar configurations.

Key specifications

How to use

Position the Rittal mounting kit at the required location inside the enclosure aligning the kit so that it supports the three-pole busbar with a 100 mm centre distance. Secure the kit according to the cabinet manufacturer's instructions, using appropriate fasteners and torque values for the enclosure material. Insert the busbar into the support groove or clamp area ensuring proper seating and alignment, then complete electrical connections following applicable standards and safety procedures. Verify mechanical stability and clearance to live parts before energising the system.

Recommendations

Use the mounting kit only within the specified busbar dimensions (30–60 mm width, up to 10 mm thickness) and maintain required creepage and clearance distances inside the cabinet. Avoid exposure to aggressive chemicals beyond typical industrial cleaners and verify compatibility with the specific environment. Follow Rittal and local electrical installation standards for fastening, earthing and live-part protection.
