RCBO for single-phase final circuits
The Siemens 5SV9316-7FM20 is a compact residual-current circuit breaker with overcurrent protection (RCBO) rated Icn 6 kA, 1P+N, type A, 30 mA residual sensitivity, C-characteristic, In 20 A, Un AC 240 V. The reduced i²t design limits let-through energy, helping with downstream selectivity in distribution boards.
Type A residual-current detection means it trips on sinusoidal AC faults and pulsating DC faults up to 6 mA — common with single-phase rectified loads (switch-mode supplies, LED drivers, washing machines). The 30 mA sensitivity covers personnel protection (IEC 60364).
Lifecycle stage is listed as current.
