Product information

Description

The Siemens SIRIUS ACT 3SU1000-4BF11-0AA0 is a professional-grade key-operated switch engineered for reliable control in industrial environments. Designed with a standard 22mm mounting diameter, this unit features a robust black plastic front ring and a secure key mechanism. It provides two distinct switching positions, O-I, with a 90-degree rotation, making it an essential component for machine activation, safety interlocks, and restricted access control within automation systems.

Advantages

This key-operated switch stands out due to its high durability and resistance to harsh industrial conditions. The SIRIUS ACT series is known for its modular design, which allows for quick and straightforward installation into standard control panels. The use of high-quality materials ensures a long service life and consistent performance, while the key-operated mechanism provides an added layer of security by preventing unauthorized operation of machinery or equipment.

Suitable for

  • Industrial control panels and automation cabinets
  • Machine start and stop operations
  • Restricted access control for sensitive equipment
  • Safety-critical switching applications

When it may not be suitable

This switch is not intended for applications requiring more than two switching positions or for environments where a non-key-operated manual toggle is preferred. It is also not suitable for outdoor installations without additional protective housing to ensure the required ingress protection rating.

Key specifications

  • Mounting diameter: 22mm
  • Switching positions: 2 (O-I)
  • Rotation angle: 90 degrees
  • Material: Plastic front ring
  • Color: Black

How to use

To install the switch, insert the actuator into a standard 22mm hole on the control panel and secure it using the provided locking nut. Once mounted, attach the necessary contact blocks to the rear of the actuator. To operate, insert the key and rotate it 90 degrees between the O and I positions to trigger the connected electrical circuit.

What to consider before purchase

  • Ensure the 22mm mounting hole is available on your control panel
  • Verify that the two-position O-I functionality meets your circuit requirements
  • Confirm if additional contact blocks are needed for your specific wiring configuration

Usage recommendations

Always ensure that the power supply is disconnected before installing or performing maintenance on the switch to prevent accidental electrical contact.
