The Siemens 5SV9316-6PK40 is a SENTRON RCD-operated circuit breaker (RCBO) combining overcurrent protection and residual current detection in a single 2-pole, 1P+N module. It is rated 40 A at 30 °C with a 30 mA residual trip threshold, Type A (pulsating DC and AC sensitive), and a 6 kA breaking capacity per EN 60898 and IEC 60947-2.
The silicon-free construction matters for potting or conformal-coating processes in sensitive electronics environments.
Thermal derating and environmental limits
Derate to 38 A at 40 °C, 36.8 A at 45 °C, 36 A at 50 °C, and 34.8 A at 55 °C. Operating ambient range is -40 to 75 °C, with max 95% humidity.
