This derates as temperature climbs — at 40 °C it's 5.7 A, at 50 °C it's 5.4 A, and at 70 °C it drops to 4.62 A. The C-curve (tripping characteristic class C) means magnetic trip occurs at 5–10 times rated current — 30–60 A for this 6 A unit. That's the standard choice for general-purpose distribution with motor or capacitive loads. The energy limitation class is 3, which keeps let-through energy low enough to protect downstream wiring and connected equipment. ## Where it goes in the panel The housing is IP20 rated only when the distribution board is installed and conductors are connected, so it's not for open-panel or washdown environments.","metaTitle":"Siemens SENTRON 5SU1656-1KK06 RCBO, 6A C-curve, 6/25kA, 2-po","metaDescription":"Siemens 5SU1656-1KK06 SENTRON RCBO, 6A rated, C-curve, 6kA (EN 60898) / 25kA (IEC 60947-2), 2-pole 1P+N.
