At 40 °C it derates to 9.5 A, at 50 °C to 9 A, and at 70 °C to 8 A. The mounting position is unrestricted, but the IP20 rating assumes the distribution board is installed with conductors connected; open-back enclosures void that protection. At 36 mm wide (2 MW) and 77 mm deep (70 mm installation depth), it occupies standard DIN-rail space — two adjacent 18 mm slots. Supply can enter from top or bottom, which simplifies busbar routing in a crowded enclosure.","metaTitle":"Siemens 5SU1354-4KK10 SENTRON RCBO, C-curve 10A, 10kA","metaDescription":"Siemens SENTRON 5SU1354-4KK10 RCBO, 1P+N, C-curve 10A, 10kA (EN 60898) / 20kA (IEC 60947-2), 2 MW, IP20.
