## Long description

Rittal AS 4055.750 is a round enclosure stamp/actuator with a 21.5 mm diameter in red, designed as a panel element for control cabinets and electrical enclosures. It functions as a user-interface component for switches or indicators and is suitable for industrial panels where a durable, color-coded actuator is required. Together with compatible dies, the stamp system can be used to punch round holes in busbars with diameters from 6.6 mm up to 21.5 mm.
Advantages
The Rittal 21.5 mm round actuator provides a standardized size that fits common control-panel cutouts and offers visible color coding in red for safety and quick identification. Its construction is intended for industrial environments and integrates with panel fittings to create a neat, professional interface. The ability to combine the actuator with dies for punching holes in busbars adds installation flexibility when preparing control enclosures.
Suitable for
 Control cabinets and electrical enclosures requiring a round 21.5 mm actuator
 Applications needing a visible red operator element for emergency or status indication
 Industrial panels where standardized panel cutouts and robust components are required
 Installation workflows that include punching holes in busbars with dies (6.6–21.5 mm)
When it may not be suitable
This actuator is not suitable when a different diameter or shape is required for the panel cutout; it specifically fits a 21.5 mm round opening. If an integrated switch, illumination, or specific electrical contact configuration is needed, verify compatibility with the chosen switch mechanism or use a combined actuator-switch unit instead.
Key specifications
 Actuator shape: round
 Actuator diameter: 21.5 mm
 Color: red
 Mounting type: panel element for control cabinets and enclosures
 Compatible hole punching range with dies: 6.6 mm to 21.5 mm
 Intended use: user-interface component for switches or indicators in industrial panels
How to use
Place the actuator into the prepared 21.5 mm round panel cutout and secure it according to the enclosure manufacturer's instructions or the switch assembly guidelines. If creating holes in busbars, select the appropriate die size and use the stamping/punching tool to produce a clean round hole between 6.6 mm and 21.5 mm. After mounting, verify mechanical retention and ensure the actuator correctly engages the underlying switch or indicator before commissioning.
What to consider before purchase
 Confirm the panel cutout diameter is 21.5 mm to ensure proper fit
 Check compatibility with the chosen switch or indicator mechanism and any required mounting hardware
 Verify that a red actuator meets the visual coding or safety requirements of your application
 Determine whether dies and punching tools are needed to prepare busbar holes and obtain compatible sizes
Usage recommendations
Use the Rittal AS 4055.750 actuator with matching switch units and mounting accessories from the same product family when possible. When punching busbar holes, follow the die manufacturer's instructions and wear appropriate personal protective equipment. Inspect the mounted actuator for secure seating and unobstructed operation during routine maintenance.
