Siemens 3SU1050-4BP61-0AA0 RONIS Key-Operated Switch, 3-Position I>O-II, 22mm

The Siemens 3SU1050-4BP61-0AA0 is a high-quality, round key-operated switch designed for secure control in industrial environments. Featuring a robust metal construction with a shiny finish, this device is engineered for standard 22mm mounting holes. It utilizes a reliable RONIS lock mechanism, identified by lock number SB30, and comes equipped with two keys to ensure authorized access and operational safety. The switch supports a 3-position I>O-II configuration, providing versatile control options for complex electrical systems and machinery.

Advantages

This key-operated switch offers exceptional durability and resistance to harsh industrial conditions due to its high-grade metal housing. The integration of the RONIS locking system provides a high level of security, preventing unauthorized personnel from operating critical machinery. Its standardized 22mm design ensures compatibility with most industrial control panels, facilitating quick and efficient installation. The clear I>O-II switching logic allows for intuitive operation, while the included set of keys ensures that the system is ready for immediate deployment.

Suitable for

• Industrial automation control panels
• Machinery safety and access control
• Electrical distribution systems
• Equipment requiring restricted operational access

This switch may not be suitable for applications requiring non-locking operation or environments where the key must be removable in all three positions, as the locking logic is specific to the I>O-II configuration. It is also not intended for outdoor use without appropriate protective enclosures to prevent environmental degradation.

Key specifications

• Mounting diameter: 22 mm
• Switch positions: 3 (I>O-II)
• Lock type: RONIS SB30
• Material: Shiny metal
• Included accessories: 2 keys

To install the switch, insert the unit into a standard 22mm hole on the control panel and secure it using the provided mounting hardware. Ensure the electrical contacts are wired according to the specific requirements of your control circuit. Once installed, the switch is operated by inserting the RONIS key and rotating it to the desired position to toggle the electrical state between the three available settings.

What to consider before purchase

• Verify that the 22mm mounting hole size is compatible with your existing panel layout.
• Confirm that the I>O-II switching logic aligns with your specific control requirements.
• Ensure that the SB30 lock type meets your facility's security and key management standards.

For optimal longevity and performance, ensure the key is fully inserted before turning and avoid using excessive force when switching between positions. Regularly inspect the lock mechanism for debris to maintain smooth operation.
