The Siemens 3SU1000-0AA50-0AA0 is a SIRIUS ACT pushbutton actuator designed for 22 mm control and signalling applications. It features a round, flat blue plastic button with a latching action and push-to-release mechanism, making it suitable for industrial operator panels, control stations and machine interfaces where clear manual actuation is required.

Built with a black plastic front ring and a compact 29.5 mm outer diameter, this actuator is intended for round mounting openings with a 22.3 mm installation diameter. It supports use with compatible contact modules and is not designed for illumination. The unit offers a high level of environmental protection, with IP66, IP67 and IP69/IP69K ratings, as well as NEMA 1, 2, 3, 3R, 4, 4X, 12 and 13 protection classifications.

Engineered for demanding industrial environments, the 3SU1000-0AA50-0AA0 provides a typical mechanical service life of 500,000 operating cycles and supports a maximum operating frequency of 1,800 operations per hour. It operates across an ambient temperature range of -25 °C to +70 °C and can be stored between -40 °C and +80 °C. Its robust construction, compact dimensions and compatibility with the Siemens 3SU1 range make it a practical choice for control panel assemblies requiring a durable blue latching pushbutton.

The component carries NEMA ratings 1, 2, 3, 3R, 4, 4X, 12 and 13.

What operating temperature range is specified?

The specified operating temperature range is -25 °C to +70 °C.

What storage temperature range is specified?

The specified storage temperature range is -40 °C to +80 °C.

What is the typical mechanical service life?

The typical mechanical service life is 500,000 operating cycles.

What is the maximum operating frequency?

The maximum operating frequency is 1,800 operations per hour.

What material is used for the actuator and front ring?

Both the actuator and the front ring are made from plastic. The actuator is blue and the front ring is black.

Is it suitable for railway-related applications?

The datasheet lists railway application ratings according to EN 61373 Category 1, Class B for shock and vibration resistance.
