The 300 mA residual current trip is for fire protection or equipment protection, not personnel shock protection (that's 30 mA or less). Type A detects sinusoidal AC faults and pulsating DC faults, covering most modern electronic loads like VFDs, switched-mode supplies, and LED drivers. The 10 kA short-circuit current rating tells you it can safely interrupt a fault up to that level per IEC 61008-1; the 1 kA rating per EN 60898 is a different standard's test — the 10 kA figure governs actual panel coordination. The 2-pole design switches both line and neutral, which is standard for single-phase 230 V installations. Mounting position is any, which is unusual for an RCCB; most require vertical orientation. Depth is 70 mm, so it fits standard 80 mm deep enclosures. Supply can come from top or bottom.","metaTitle":"Siemens 5SM3618-6KK SENTRON RCCB, 2-pole, 100 A, 300 mA, Typ","metaDescription":"Siemens SENTRON 5SM3618-6KK RCCB, 2-pole, 100 A, 300 mA residual current, Type A, 230 V AC, 10 kA SCCR.
