3KD9103-7 SIEMENS

The 3KD9103-7 auxiliary switch module from Siemens is specifically designed as an accessory for 3KD size 1/2, 3KF size 1, and 3KC0 size 1/2 circuit breakers. This module enhances the functionality of the circuit breaker by providing the capability to integrate up to two auxiliary switches. These auxiliary switches are leading, meaning they change state slightly before the main contacts of the circuit breaker. A key feature of this module is its integrated test function, which allows for convenient verification of the auxiliary switch operation without needing to trigger the main circuit breaker. This test function ensures the reliability and proper functioning of the auxiliary switches in critical applications. The module is easily installed and connected to the corresponding circuit breaker, providing a seamless integration for monitoring and control purposes. It is ideal for applications where remote indication of the circuit breaker status or control signals are required. The robust design ensures reliable performance in demanding industrial environments. This auxiliary switch module provides a cost-effective solution for enhancing circuit breaker functionality.
