5ST3022-2 SIEMENS

The 5ST3022-2 from Siemens is a fault signal contact designed to enhance the monitoring capabilities of your circuit protection devices. This auxiliary component provides a reliable means of remotely indicating the status of your miniature circuit breakers (MCBs) and residual current circuit breakers with overcurrent protection (RCBOs). Featuring two normally closed (2NC) contacts, the fault signal contact immediately signals a fault condition, enabling prompt response and minimizing downtime. It is compatible with Siemens 5SL, 5SY, and 5SP MCBs, as well as 5SU1 RCBOs and 5SV residual current devices (RCDs). For seamless integration with 5SU1 devices, the 5ST3805-1 handle coupler is required, ensuring a secure and reliable connection. The inclusion of a test and acknowledgment key allows for convenient testing of the fault signaling circuit and acknowledgment of cleared faults. This feature streamlines maintenance procedures and ensures the continued reliability of the system. By providing remote fault indication, the 5ST3022-2 enables proactive maintenance and reduces the risk of prolonged equipment downtime. Its robust design and compatibility with a range of Siemens circuit protection devices make it a versatile and valuable addition to any electrical installation. This device enhances safety and operational efficiency.
