Temperature derating is published: at 40 °C ambient the continuous rating drops to 23.5 A, at 50 °C to 21.75 A, and at 70 °C to 18.25 A. For a panel builder loading a board near its thermal limit, this curve is the number that governs the actual circuit capacity — not the 25 A label. The 77 mm depth (70 mm installation depth) fits standard enclosures with door-mounted equipment; the 90 mm height clears typical busbar shrouds. Supply can enter from either top or bottom, which simplifies busbar routing in a crowded board. Rated IP20 with conductors connected and the distribution board installed — standard for enclosed panel use.","metaTitle":"Siemens 5SU1354-0KK25 SENTRON RCBO, 25A, 30mA, Type B, 10kA","metaDescription":"Siemens 5SU1354-0KK25 SENTRON RCBO, 1P+N, 25 A rated, 30 mA residual, 10 kA breaking capacity, Type B characteristic.
