It protects a single-phase final circuit with a rated current of 6 A at 230/240 V, 50 Hz, tripping characteristic B (3–5× In for short-circuit and overload). The residual-current element is instantaneous, meaning no intentional delay — it trips as soon as the earth-fault threshold is exceeded, which is standard for socket-outlet circuits and general-purpose final subcircuits where rapid disconnection is required. Energy limitation class 3 keeps the let-through energy low enough to protect downstream wiring and connected loads. ## Temperature derating — the real-world rating Above that, the continuous current must be derated: 5.7 A at 40 °C, 5.4 A at 50 °C, 5.1 A at 60 °C, and 4.62 A at 70 °C. If this RCBO lives in a non-air-conditioned panel or a hot machine cabinet, the 40 °C or 50 °C row is the one that governs the load calculation — not the 30 °C headline. Maximum operating temperature is 75 °C; minimum is -40 °C, covering cold storage or outdoor enclosures. Width of 36 mm (2 modular units) snaps onto standard DIN rail. Depth is 77 mm, installation depth 70 mm.","metaTitle":"Siemens 5SU1356-0KK06 SENTRON RCBO, B-Curve 6A, 1P+N, 6kA","metaDescription":"Siemens SENTRON 5SU1356-0KK06 RCBO, 1P+N, B-curve 6 A, 6 kA per EN 60898, 25 kA per IEC 60947-2.
