Depth is 77 mm, installation depth 70 mm — check your enclosure's gland-plate clearance; some shallow consumer units need the 70 mm figure. Mount in any position, feed from top or bottom. IP20 only with conductors connected and the distribution board installed, so it's strictly indoor panel use. At 40 °C it's 18.8 A; at 50 °C it's 17.4 A; at 60 °C it's 16.2 A; at 70 °C it's 14.6 A.","metaTitle":"Siemens SENTRON 5SU1354-1KK20 RCBO, 20 A C-curve, 10 kA","metaDescription":"Siemens SENTRON 5SU1354-1KK20 RCBO, 1P+N, 20 A, C-curve, 10 kA per EN 60898, 20 kA per IEC 60947-2. 36 mm wide, IP20.
