Enclosure accessory Rittal AS 4055.777 metallic, round 17.5 mm matrix

Rittal AS 4055.777 metallic, round 17.5 mm matrix is a compact enclosure accessory designed for creating 17.5 mm circular hole patterns in control cabinets, busbars and enclosure panels. The part is supplied as a lightweight metal processing matrix and is intended for use with matching male dies. It provides a ready-made solution when round holes of 17.5 mm diameter are required for fittings, connectors or cable entry points in electrical enclosures.

Advantages

The metallic matrix is durable and dimensionally stable for repetitive use in punching operations. It is lightweight for easy handling and installation, and compatible with the corresponding male die to ensure precise, uniform round holes. Using a purpose-built matrix reduces manual marking and cutting, improving repeatability and alignment across multiple panels.

Suitable for

• Punching 17.5 mm round holes in enclosure panels and busbars
• Preparation of control cabinet doors and mounting plates for circular fittings
• Small batch or field processing where a compact, portable die is needed

When it may not be suitable

This female die must be used in combination with the respective male die; it is not a standalone holemaking tool. It is intended for applications requiring a 17.5 mm round pattern only and is not suitable for larger or non-circular hole shapes. For high-volume production or thicker material beyond the die’s rated capability, a different industrial press or tooling set may be more appropriate.

Key specifications

• Hole diameter: 17.5 mm (round)
• Material: metallic construction suitable for punching operations
• Weight (packaged): approx. 290 g
• Intended use: female die for combination with corresponding male die for punching busbars and panels

How to use

Position the female matrix in the desired location on the panel or busbar and align it with the matching male die. Use appropriate press equipment or hand-operated tooling rated for the die set to perform the punching operation. Ensure the workpiece is clamped securely, check alignment before each operation, and follow the press manufacturer’s safety and operating instructions. After punching, remove burrs and inspect the hole for dimensional accuracy.

What to consider before purchase

• Compatibility with the corresponding male die and your press or tooling system
• Material thickness range the die can process safely
• Required hole diameter is 17.5 mm and matches your fitting or connector dimensions

Usage recommendations

Use the Rittal AS 4055.777 female matrix only with the correct male die and within the material thickness limits recommended by your press. Verify alignment and clamp workpieces securely to achieve clean round holes and extend tool life. Regular inspection and maintenance of the die surfaces will maintain precision over repeated use.
