It is rated for 10 kA breaking capacity per EN 60898 and 20 kA per IEC 60947-2, meaning it can safely interrupt fault currents up to those levels in a residential or commercial distribution board. The unit occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 77 mm and an installation depth of 70 mm. Supply can be connected from either the top or bottom, which simplifies panel wiring when busbar routing dictates the feed direction. ## Temperature derating and installation constraints The 16 A rating is valid at 30 °C ambient. At elevated panel temperatures the continuous current must be derated: 15.2 A at 40 °C, 14.4 A at 50 °C, 13.6 A at 60 °C, and 12.32 A at 70 °C. If the RCBO is mounted in a crowded enclosure or near heat-generating devices, use the 40 °C or 50 °C column as the design limit — the 30 °C figure is only safe in a well-ventilated, uncrowded board. The operating range spans -40 °C to 75 °C, so it handles outdoor enclosures in cold climates as long as the IP20 rule is respected.","metaTitle":"Siemens 5SU1354-0LB16 SENTRON RCBO, 2-pole, 16 A, Type B, 10","metaDescription":"Siemens 5SU1354-0LB16 SENTRON RCBO, 2-pole, 16 A rated, Type B trip, 10 kA (EN 60898) / 20 kA (IEC 60947-2), residual current Type AC, 36 mm wide, IP20.
