Enclosure accessory Rittal AS 4055.772, metallic finish, mounting matrix 9.5 mm round

Rittal AS 4055.772 is an enclosure accessory with a metallic finish designed for use in control cabinets, enclosures and industrial panels. It comprises a 9.5 mm round mounting matrix that enables the formation of precise round openings and mounting points when paired with the corresponding male die. The component is intended for integration within Rittal systems and compatible setups where clean, repeatable round holes in sheet metal or busbars are required.

Advantages

The metallic finish provides durable corrosion resistance and a uniform appearance that aligns with professional electrical and enclosure installations. The 9.5 mm round matrix offers accurate diameter control for consistent hole quality when used with the matching male die. Its lightweight construction simplifies handling during installation and it is designed to work reliably as part of a die set for punching round holes in busbars and thin sheet materials.

Suitable for

• Punching precise 9.5 mm round holes in busbars when used with the appropriate male die
• Creating mounting points or cable entry holes in control cabinet panels and enclosures
• Integration into Rittal systems or other compatible industrial panels and sheet-metal assemblies

When it may not be suitable

This accessory is intended to be used together with the respective male die; it cannot form holes on its own and therefore is not suitable as a standalone punching solution. It is designed for thinner sheet materials and busbars; for thicker materials or non-metal substrates, alternative tooling or processes may be required.

Key specifications

• Finish: metallic
• Die type: female round matrix
• Round hole diameter: 9.5 mm
• Application: punching round holes in busbars and thin sheet metal when combined with corresponding male die
• Construction: lightweight metal suitable for integration into die sets

How to use

Install the female matrix into the appropriate die holder or press unit according to the press manufacturer's instructions. Fit the matching male die precisely opposite the female matrix to form a die set. Position the busbar or sheet-metal panel between the dies, align the intended hole location, and operate the press to punch the round hole. After punching, inspect the hole edge for burrs and deburr if necessary. Follow safety guidelines and use appropriate personal protective equipment when working with press tools and sheet metal.

What to consider before purchase

• Confirm compatibility with your press or die holder system and the specific male die required for 9.5 mm round holes
• Verify material thickness limits for effective punching in busbars or sheet metal
• Consider whether a die set or additional tooling is needed to perform the punching operation

Usage recommendations

Use the male and female dies as a matched set in a compatible press; ensure correct alignment and appropriate machine settings for the material thickness. Regularly inspect dies for wear and maintain tooling to ensure consistent hole quality and safe operation.
