3KD9103-1 SIEMENS

The 3KD9103-1 auxiliary switch from Siemens is a crucial accessory designed to enhance the functionality and monitoring capabilities of Siemens circuit breakers. Specifically engineered for compatibility with 3KD size 1/2, 3KF size 1, and 3KC0 size 1/2 circuit breakers, this auxiliary switch provides a reliable means of signaling the breaker's status. Featuring a single change-over contact (1CO), the switch accurately reflects the breaker's position, indicating whether it is open, closed, or tripped. This real-time status indication is invaluable for remote monitoring, control systems, and alarm circuits, ensuring prompt awareness of any changes in the circuit breaker's state. The inclusion of a 500mm connecting cable simplifies installation, offering flexibility in positioning the switch within the electrical panel or control cabinet. This auxiliary switch enables seamless integration with monitoring systems, allowing for comprehensive oversight of electrical distribution networks. By providing clear and immediate feedback on the circuit breaker's condition, the 3KD9103-1 contributes to improved safety, reduced downtime, and enhanced operational efficiency. Its robust design and precise engineering ensure reliable performance in demanding industrial environments, making it an essential component for modern electrical protection systems. This auxiliary switch is a testament to Siemens' commitment to quality and innovation in electrical engineering.
