It's rated for 230/240 V AC at 50 Hz and breaks faults up to 4.5 kA per EN 60898. At 40 °C it's 5.7 A, at 50 °C it's 5.4 A, and at 60 °C it drops to 5.1 A. If your distribution board runs hot — say 55 °C internal ambient from adjacent loads — you're down to 5.22 A continuous. That matters for BOM accuracy: a 6 A RCBO on a 5.5 A continuous load in a 50 °C panel is already at 100% utilization. Leave headroom or step up one frame size. ## Mounting and integration — DIN rail, any position, top or bottom feed The supply can enter from either top or bottom — no mandatory orientation. Mounting position is unrestricted, so it fits in tight enclosures where you're rotating rows to save space.","metaTitle":"Siemens 5SU1353-1KL06 SENTRON RCBO, 6A C-curve 1P+N 4.5kA","metaDescription":"Siemens SENTRON 5SU1353-1KL06 RCBO, 6A rated, C tripping characteristic, 1P+N, 4.5 kA breaking capacity per EN 60898.
