Siemens 3SB3000-3BJ01

The Siemens 3SB3000-3BJ01 is a key-operated switch designed with a durable plastic housing and a round shape. This model features a two-position operation, allowing the key to be removed only when in the zero (off) position, providing added security and control. Although this particular switch has been discontinued since September 2019, it may still be available through distributors such as BSP Automation for specific applications or maintenance needs. Its reliable design makes it suitable for various control and safety functions in industrial environments.
