## Summary description

Rittal AS 4055.745 is a red, round enclosure seal plug with a 13.5 mm diameter designed for closing unused cut-outs in electrical cabinets and control enclosures.

## Long description

Rittal AS 4055.745 is a red, round enclosure seal plug with a 13.5 mm diameter, designed to close unused cut-outs in electrical cabinets and control enclosures. The plug provides a simple, visible closure that helps prevent dust ingress and accidental contact with internal components. Manufactured for compatibility with standard panel cut-outs, it is intended for installations and maintenance where reliable, temporary or permanent closure of panel openings is required.
Advantages
The seal plug is made from durable insulating material that resists aging and typical environmental influences found in indoor electrical installations. Its round shape and snug fit ensure a secure closure without special tools for insertion, while the red color provides clear visual identification of sealed openings. The component is lightweight and requires minimal storage space, making it convenient for field technicians and panel builders.
Suitable for
 Closing unused round cut-outs in electrical cabinets and control panels
 Temporary or permanent sealing during installation and maintenance work
 Areas where prevention of dust entry and accidental contact to live parts is needed
 Applications requiring quick, tool-free installation of protective plugs
When it may not be suitable
The plug is intended for standard panel cut-outs of the specified diameter; it may not provide an effective seal on nonstandard or deformed openings. It is not a substitute for gaskets or seals designed for IP-rated enclosures where specific ingress protection classes are required unless the overall enclosure design and additional sealing measures meet the necessary IP rating.
Key specifications
 Shape: Round
 Color: Red
 Nominal diameter: 13.5 mm
 Material type: Insulating polymer (durable for indoor electrical applications)
 Mounting: Push-fit insertion into panel cut-out
How to use
Ensure the panel cut-out matches the plug diameter and that edges are free of burrs or sharp remnants. Align the plug with the hole and press it into the opening until it seats flush with the panel surface; no special tools are normally required. For removal, pry gently from the edge using a suitable non-conductive tool to avoid damaging the panel or the plug. Follow standard safety procedures and de-energize circuits when working near live components.
What to consider before purchase
 Verify the panel hole diameter is compatible with a 13.5 mm round plug
 Confirm color and visibility requirements for your installation
 Check whether the enclosure requires a certified IP rating or specific gasketed seals
 Assess whether a permanent or removable closure is preferred
Usage recommendations
For reliable results, store plugs in a dry environment away from direct sunlight, and inspect panels for proper fit before final installation. Use non-conductive tools for insertion and removal near live equipment and combine with appropriate sealing measures if the application requires a defined ingress protection level.
