Enclosure Accessory Rittal AS 4055.744 — red, stamp 11.5 mm round

Rittal AS 4055.744 is a red enclosure accessory in the form of a round stamp with an 11.5 mm imprint diameter, designed for use in electrical and industrial cabinets. Intended for marking or labelling components and cable entries, the stamp integrates with compatible Rittal enclosures and panels and can be used together with dies to punch round holes in busbars with diameters from 6.6 mm to 21.5 mm.

Advantages

The red round stamp offers a compact, ready-to-install solution for consistent visual identification of terminals, cable entries and panel features. Its standardized 11.5 mm imprint ensures uniform labelling across multiple enclosures, while compatibility with dies enables precise punching of round holes in busbars. The lightweight design simplifies handling during assembly and maintenance work in control cabinets.

Suitable for (tasks / use cases)

• Marking and labelling cable entries, terminals and connector positions inside electrical enclosures
• Use with dies to punch round holes in busbars with diameters between 6.6 mm and 21.5 mm
• Installation and maintenance tasks in industrial control cabinets and distribution panels
• Standardizing identification across multiple Rittal panels and enclosures

When it may not be suitable

This round stamp is intended primarily for marking and light mechanical punching tasks in electrical panels. It is not a substitute for heavy-duty hole-making tools or large-format labelling systems. If you require imprint sizes other than 11.5 mm or a colour different from red, this specific accessory may not meet your needs.

Key specifications

• Colour: red
• Imprint diameter: 11.5 mm (round)
• Application: marking and stamping for enclosures and panels
• Compatible hole punching range (with dies): round holes 6.6 mm to 21.5 mm in busbars
• Suitable environments: electrical and industrial cabinets, control panels

How to use

Install the stamp into the appropriate holder or accessory point on the enclosure or panel according to the enclosure manufacturer's mounting instructions. For punching holes in busbars, fit the correct die to the stamp assembly and position the stamp over the intended punch location. Apply controlled force as specified by the die and tool combination to form the round hole. Use the stamp without dies for visual imprinting and labelling of component positions, ensuring alignment before each impression.

What to consider before purchase

• Confirm that the 11.5 mm round imprint size matches your labelling or identification requirements
• Verify compatibility with your Rittal enclosure model and any holders or mounting points used for stamps
• Check which dies are required for the desired hole diameters in busbars (6.6 mm to 21.5 mm range) and whether they are included or must be purchased separately
• Ensure the red colour and physical dimensions suit your panel design and standards

Usage recommendations

Use appropriate personal protective equipment when punching holes in metal parts and follow the die and tool manufacturer’s guidance for force and alignment. For consistent labelling, test the stamp on a spare panel or material to confirm impression quality before series application.
