STPS500 Pyrotechnic Circuit Breaker

Introducing the PyroFuse from Sensata Technologies – the ultimate high-voltage safety solution. The STPS500 series PyroFuse is specifically designed to support a wide range of high-voltage applications, including automotive, charging, aerospace, and industrial systems. In the event of a short circuit or accident, the device quickly disconnects the load, safeguarding both the electrical system and the safety of drivers and passengers. It offers key features such as high continuous current-carrying capability, rapid response time, high breaking capacity, excellent post-isolation resistance, and a fully enclosed housing that prevents gas release during interruption events. These features work together to enhance overall system safety and reliability, all in a lightweight, compact design that integrates seamlessly without adding significant weight or bulk. Highlights • Max continuous current 500A. • Max breaking capacity: 1) 500V/20000A @14uH. 2) 1000V/16000A @16uH. • Bi-directional device • Irreversible current separation Features Active safety with external trigger Fast disconnect <1ms High post IR >50MΩ @ 1000V Lightweight design and small form factor Applications Battery disconnection to prevent fire or damage from short circuits or electrical shock during/after accident. For high voltage applications in electric vehicles, aerospace (including eVTOL) and industrial.
