Siemens 5SU1324-6FA20 SENTRON RCBO — 20 A, 30 mA, B Curve
The Siemens 5SU1324-6FA20 is a 2-pole RCBO from the SENTRON series, combining overcurrent protection and residual current detection in a single 3-module-width unit.
The 20 A rating is thermally calibrated at 30 °C ambient; at 40 °C the continuous current derates to 18.8 A, at 50 °C to 17.4 A, and at 70 °C to 14.6 A — factor this into panel thermal design if the distribution board runs warm. For installations where the available fault current exceeds 10 kA, an upstream current-limiting MCB or fuse is required to coordinate selectivity.
Mounting position is unrestricted. Supply can enter from either top or bottom.
