The Siemens 5SV9316-7CN16 is a 1P+N RCD-operated circuit breaker from the SENTRON 5SV9 series — an RCBO that combines overcurrent and residual-current protection in a single 18 mm wide module. The Type A fault-current detection means it catches pulsating DC residual currents from electronics, rectifiers, and variable-speed drives, not just sinusoidal AC faults.
At 40 °C it derates to 15.2 A, at 45 °C to 14.72 A, at 50 °C to 14.24 A, and at 55 °C to 13.76 A. If the panel runs warm — say a crowded enclosure near a conveyor drive cabinet — size the branch circuit for the actual ambient, not the 30 °C headline number.
