In a warm panel — say 45 °C — the continuous current drops to 14.8 A; at 60 °C it's 13.4 A. At the maximum rated 70 °C ambient, the RCBO is good for 12.5 A. This derating curve matters when the breaker shares a crowded enclosure with other heat sources. The IP20 rating applies when the distribution board is installed with connected conductors — this is standard for enclosed panel gear, not for exposed outdoor use. Supply can enter from either top or bottom.","metaTitle":"Siemens 5SU1646-7FP16 SENTRON RCBO, 4P C-16A 6kA","metaDescription":"Siemens 5SU1646-7FP16 SENTRON RCBO, 4-pole, C-curve 16 A, 6 kA per EN 60898, 400 V AC.
