The Siemens 5SV9316-7CN06 is a 1P+N RCD-operated circuit breaker (RCBO) from the SENTRON 5SV9 series, combining overcurrent protection and residual current detection in a single 18 mm wide module.
Ambient temperature range of -25 to +55 °C covers most indoor panel environments, but the current derating curve matters: 6 A at 30 °C drops to 5.64 A at 40 °C, 5.46 A at 45 °C, 5.22 A at 50 °C, and 5.04 A at 55 °C. If your panel runs hot, size the upstream breaker for the derated value.
