5ST302-FC SIEMENS

The 5ST302-FC fault signalling contact from Siemens provides comprehensive monitoring for miniature circuit breakers (MCBs) and residual current circuit breakers with overcurrent protection (RCBOs). Designed for use with Siemens 5SL, 5SY, and 5SP MCBs, as well as 5SU1 RCBOs and 5SV residual current devices (RCDs), this auxiliary contact enhances circuit protection systems. It features one normally open (NO) contact and one normally closed (NC) contact, offering versatile signalling options for remote indication of fault conditions. This allows for immediate awareness of tripped breakers, enabling prompt troubleshooting and minimizing downtime. The 5ST302-FC facilitates improved system reliability and safety by providing real-time feedback on circuit status. Its compact design ensures easy integration into existing electrical panels without requiring significant space. By using this fault signalling contact, users can proactively manage their electrical systems and prevent potential hazards. This device is an essential component for applications where continuous monitoring and rapid response to faults are critical.
