The conditional short-circuit rating per IEC 61008-1 is 0.5 kA when backed by a specific upstream fuse or MCB — check coordination with the branch breaker. ## Residual current type and switching characteristics For circuits with variable-speed drives, LED lighting, or other non-linear loads that generate pulsed DC leakage, a Type A or Type F RCCB is required. The design is instantaneous with no short-time delay, so it trips within milliseconds of the fault exceeding 30 mA. Silicon-free construction suits environments where silicone outgassing can contaminate contacts or optics.","metaTitle":"Siemens 5SV4314-0MB SENTRON RCCB, 40 A, 30 mA, 2-pole","metaDescription":"Siemens 5SV4314-0MB SENTRON RCCB, 40 A rated, 30 mA trip, Type AC, 10 kA SCCR, 2-pole, 230 V AC, 60 Hz.
