5ST3022 SIEMENS

The 5ST3022 fault signal contact from Siemens provides reliable remote signaling of miniature circuit breaker (MCB) and residual current circuit breaker (RCBO) status. This auxiliary switch features two normally closed (NC) contacts, enabling clear indication of tripped or fault conditions. It is specifically designed for use with Siemens 5SL, 5SY, and 5SP miniature circuit breakers, as well as 5SU1 RCBOs and 5SV residual current devices (RCDs). When used with 5SU1 RCBOs, the 5ST3805-1 handle coupler is required for proper mechanical connection. The fault signal contact facilitates remote monitoring of circuit breaker status in various applications. This allows for prompt response to faults, improving system reliability and minimizing downtime. Its compact design enables easy integration into existing electrical panels. The 5ST3022 enhances safety and operational efficiency by providing immediate notification of circuit interruptions. This is crucial for maintaining continuous operation and preventing potential hazards. It is an essential component for comprehensive circuit protection and monitoring systems.
