Supply can enter from either top or bottom, simplifying panel layout. The IP20 rating applies once installed in a distribution board with conductors connected — not for exposed outdoor use. ## Temperature derating and real-world current At 40 °C the continuous current drops to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A.","metaTitle":"Siemens 5SU1656-1KK16 SENTRON RCBO, 16 A, 6 kA, Type C, 1P+N","metaDescription":"Siemens 5SU1656-1KK16 SENTRON RCBO, 16 A rated at 30 °C, 6 kA (EN 60898) / 15 kA (IEC 60947-2), Type C, 1P+N, 2-module width.
