The Siemens SENTRON 5SU1354-6KK06 is a 1P+N RCBO (residual current circuit breaker with overcurrent protection) rated 6 A at 30 °C with a B tripping characteristic. It breaks fault currents up to 10 kA per EN 60898 and 35 kA per IEC 60947-2, covering the typical domestic and light commercial panel requirements.
At 40 °C it derates to 5.7 A, at 50 °C to 5.4 A, and at 70 °C to 4.62 A — so in a warm enclosure the actual continuous current capacity drops. The 10 kA breaking capacity under EN 60898 is the domestic standard; the 35 kA under IEC 60947-2 gives headroom for industrial distribution where fault levels are higher. The rated insulation voltage is 264 V and the surge voltage resistance is 4 000 V, consistent with overvoltage category III and pollution degree 2 — typical for fixed-installation switchgear.
Panel integration
The 36 mm width (2 modular units) and 77 mm depth fit standard DIN-rail enclosures; installation depth is 70 mm.
