At 40 °C it derates to 115.62 A, at 50 °C to 106.25 A, and at 60 °C to 96.25 A — so a panel running warm loses roughly 23% of the headline capacity. For a 100 A continuous load in a 50 °C enclosure, the 5SU1644-6KK82 still has headroom; at 60 °C it's marginal. Snap-on DIN-rail mount, 11 modular width units wide (198 mm). Depth is 77 mm, height 90 mm. The IP20 rating applies once the distribution board is installed with conductors connected — not for open-panel wiring. Mount in any position.","metaTitle":"Siemens 5SU1644-6KK82 SENTRON RCBO, 4P, 125A, 10kA, Char B","metaDescription":"Siemens SENTRON RCBO 5SU1644-6KK82, 4-pole, 125A at 30°C, 10kA breaking capacity per EN 60898, characteristic B.
