Enclosure Accessory Rittal AS 4055.773 — Metallic finish, 11.0 mm round die

Rittal AS 4055.773 is an enclosure accessory with a metallic finish and an 11.0 mm round die intended for precision panel work on Rittal enclosures and electrical cabinets. The female die is designed to be used together with the corresponding male die to punch round holes in busbars and metal panels. Lightweight and compact, this die supports installation, maintenance and modification tasks in control cabinets and industrial panels.

Advantages

The 11.0 mm round die provides consistent, repeatable hole geometry when used with the matching male die, ensuring accurate fittings for connectors or cable passages. Its metallic finish gives durability and resistance to wear during repeated punching operations, while the compact size makes it easy to handle and position in confined cabinet spaces.

Suitable for

• Punching round holes in busbars and metal panels
• Panel modifications and retrofits in electrical cabinets
• On-site maintenance and installation work where precise hole dimensions are required

When it may not be suitable

This female die is not a standalone tool and must be used together with the corresponding male die; it will not produce holes by itself. It is designed for use on sheet metal and busbars of suitable thickness and may not be appropriate for very thick or hardened materials beyond the rated capacity of the combined die set.

Key specifications

• Die shape: round
• Nominal hole diameter: 11.0 mm
• Finish: metallic
• Intended application: punching holes in busbars and enclosure panels
• Compatibility: designed for use with the matching male die

How to use

Position the female die on the inside of the panel or busbar and align the corresponding male die on the outside. Secure the dies in the appropriate punch tool or press, ensuring correct alignment and clamping. Operate the punch according to the tool manufacturer's instructions to form a clean round hole. After punching, inspect the hole and deburr edges if necessary to prepare for component installation.

What to consider before purchase

• Ensure you have the matching male die required to complete the punch set.
• Check the sheet metal or busbar thickness to confirm compatibility with the die pair and the punching tool.
• Verify that a hand punch, hydraulic press, or compatible tool is available for use with the die pair.

Usage recommendations

Use the die pair with the correct tooling and follow safe operating procedures, including appropriate clamping and personal protective equipment. For consistent results, test on scrap material first to confirm alignment and hole quality before working on critical panels or busbars.
