Rated current derates with ambient temperature: 13 A at 30 °C, 12.48 A at 40 °C, 11.96 A at 50 °C, 10.53 A at 65 °C, and 10.01 A at 70 °C. For a panel running at 45 °C ambient, expect 12.22 A continuous — enough margin for a 10 A resistive load or a 1.5 kW motor circuit. ## Terminal capacity and wiring flexibility The supply cord can enter from either top or bottom. ## Coordination and selectivity notes Energy limiting class 3 aids downstream coordination with smaller MCBs. The type of fault current is AC, so it's not suitable for pulsating DC or smooth DC fault currents. The test circuit requires a minimum of 195 V to operate the test button.","metaTitle":"Siemens 5SU1354-1LB13 RCBO, 13 A, C-curve, 10 kA, 2-pole","metaDescription":"Siemens SENTRON 5SU1354-1LB13 RCBO, 13 A rated, C tripping characteristic, 10 kA breaking capacity per EN 60898. 2-pole 1P+N, 2 width units.
