‌1. Product Name‌
SIEMENS 3SU1000-5BL41-0AA0 Key-Operated Switch (Key Switch)

‌2. Product Introduction‌
The SIEMENS 3SU1000-5BL41-0AA0 is a key-operated switch from Siemens' SIRIUS ACT product line. It is a modular, 22mm round switch with a key-locking mechanism, designed for industrial control panels to provide secure and authorized operation. The variant "3SU1000-5BL41-0AA0-Z Y11" is a specific configuration with a black bezel.

‌3. Product Description‌
The SIEMENS 3SU1000-5BL41-0AA0 is a key-operated switch from Siemens' SIRIUS ACT series of modular actuators and indicators. Designed for 22mm mounting holes, it features a round plastic actuator head. It offers three switch positions (typically labeled I-O-II) with latching operation and a switching actuating angle of 2 x 45 degrees. The switch is supplied with two keys (lock number S-10-CG/SSG10) and allows key removal in positions I and II. It often includes laser inscription for custom labeling. This switch is engineered for reliability in industrial environments and is commonly used to control safety-critical functions or to restrict access to control modes, such as those for machinery that may incorporate ‌SIEMENS MOTOR‌ drives. By requiring a physical key for operation, it prevents unauthorized access or unintended changes to system settings, adding a layer of security and safety to motor control circuits and automation panels.

‌5. Product Advantages‌
The SIEMENS 3SU1000-5BL41-0AA0 offers key advantages centered around security, durability, and modularity. Its primary benefit is ‌enhanced security and access control‌, as it requires a physical key to operate, preventing unauthorized personnel from activating or changing critical machine functions. This is crucial for safety and operational integrity in industrial settings. As part of the SIRIUS ACT modular system, it offers high ‌design flexibility‌ and easy integration with a wide range of contact blocks, mounting frames, and other panel components. Its ‌robust construction‌ from durable plastic materials ensures reliable performance in demanding industrial environments. The ‌clear switching positions (I-O-II)‌ and latching mechanism provide tactile feedback and stable state retention. Options for ‌laser inscription‌ allow for customized labeling, improving panel clarity and reducing operator error. Its ‌standard 22mm round design‌ ensures compatibility with a vast array of industry-standard panel cutouts and accessories.
