If this RCBO sits in a crowded distribution board where ambient can reach 50 °C, plan for a 21.75 A continuous load — not 25 A. The short-time delayed K characteristic means it tolerates brief inrush without nuisance tripping, useful for motor-starter or capacitive-load circuits. Mounting position is unrestricted, and the supply can enter from top or bottom — no orientation restrictions in the cabinet.","metaTitle":"Siemens SENTRON 5SU1354-6LB25 RCBO 25A Type A 30mA 10kA","metaDescription":"Siemens SENTRON 5SU1354-6LB25 RCBO, 25A rated, Type A residual current, 30mA sensitivity, 10kA (EN 60898) / 20kA (IEC 60947-2) breaking capacity.
