The 4-pole design (all poles protected) suits three-phase loads where neutral protection is also required. In a typical enclosed panel running at 40 °C, the continuous current drops to 9.6 A; at 50 °C it's 9.1 A; at 60 °C it's 8.6 A. If your load draws a steady 9.5 A and the panel ambient hits 45 °C (9.4 A derated), you're at the margin — step up one frame or improve ventilation. The 4-module-wide footprint (72 mm) on DIN rail means this fills four 18 mm positions; plan your gland-plate layout accordingly. ## Installation notes Mounts in any position on DIN rail.","metaTitle":"Siemens SENTRON 5SU1646-6FP10 RCBO, 4P, 10 A, B-curve, 6 kA","metaDescription":"Siemens SENTRON 5SU1646-6FP10 RCBO, 4-pole, 10 A rated at 30 °C, B tripping characteristic, 6 kA breaking capacity per EN 60898.
