Enclosure/Accessory Rittal AS 4055.742, red, accessory for stamping/marking (9.5 mm round)

Rittal AS 4055.742 is a red accessory designed for stamping and marking applications in electrical enclosures and industrial cabinets. Supplied as a 9.5 mm round component, it is intended to be used with compatible dies and stamping tools to assist in panel identification, labelling and organized cable or equipment marking during installation and maintenance.

Advantages

The accessory is lightweight and colour-coded to allow quick visual identification within a set of stamping tools or during on-site work. Its 9.5 mm round shape provides a consistent marking size for labels or punched guide points. Compatibility with a range of dies enables punching of round holes from 6.6 mm up to 21.5 mm in busbars when used together with appropriate dies and stamps.

Suitable for

• Panel identification and labelling in electrical enclosures
• Marking and organisation of wiring and terminal positions
• Use with stamping tools and dies for controlled round punches in busbars
• Maintenance and installation work where colour-coded accessories speed up tool selection

When it may not be suitable

This accessory is intended specifically for stamping/marking operations and does not function as a standalone cutting or drilling tool. It requires compatible stamping dies and a press or hand-stamping tool to produce holes or marks.

For applications that need non-round shapes, larger structural modifications, or high-volume automated punching without manual tool compatibility, a different tool or accessory may be more appropriate.

Key specifications

• Colour: red
• Shape: round
• Nominal diameter: 9.5 mm (round component)
• Suitable punching range when used with dies: 6.6 mm to 21.5 mm in busbars (with appropriate dies)
• Intended use: accessory for stamping/marking in electrical panels and cabinets

How to use

Install the accessory into the compatible stamping tool according to the tool manufacturer's instructions, then select and fit the appropriate die for the desired punch diameter. Position the stamping tool over the marking location on the panel, busbar or enclosure, and operate the press or hand-stamping mechanism to create the round hole or mark. Verify the result visually and, if necessary, deburr edges or clean the surface to ensure clear identification.

What to consider before purchase

• Confirm compatibility with your stamping tool and dies.
• Verify that the 9.5 mm round size meets your labelling or marking requirements.
• Consider the required punching diameter range (6.6 mm to 21.5 mm) and whether additional dies are needed.
• Assess whether colour-coding and lightweight construction fit your on-site workflow.

Usage recommendations

Use Rittal AS 4055.742 together with manufacturer-recommended dies and a properly rated stamping tool. Wear appropriate personal protective equipment while stamping and deburr punched edges for safe handling and clear labelling results.
