Rated IP20 with conductors connected and distribution board installed. Ambient temperature range -40 °C to 75 °C, but the current must be derated above 30 °C — at 40 °C it carries 5.7 A, at 50 °C 5.4 A, at 60 °C 5.1 A, and at 70 °C 4.62 A. Halogen-free and silicon-free construction. ## Coordination & compliance Overvoltage category III, pollution degree 2, insulation voltage 264 V, surge voltage resistance 4 kV. Energy limitation class 3. The RCBO is instantaneous type (no intentional delay). For selectivity studies, the 25 kA rating under IEC 60947-2 gives better fault-clearing capability than the 6 kA EN 60898 rating — useful when coordinating with upstream breakers in a high-fault panel.","metaTitle":"Siemens 5SU1356-6KK06 SENTRON RCBO, 6A B-Curve, 6/25 kA","metaDescription":"Siemens SENTRON 5SU1356-6KK06 RCBO, 1P+N, 6 A rated at 30 °C, B-curve, 6 kA (EN 60898) / 25 kA (IEC 60947-2). 2 MW, 36 mm wide, IP20.
