The 20 kA figure gives headroom for industrial panel applications where fault currents may exceed 10 kA; the 10 kA rating covers the domestic/commercial coordination requirement. Two modules wide (36 mm), 77 mm deep, 90 mm tall. Neutral conductor is switched internally (1P+N configuration), so no separate neutral bar is needed downstream. Supply can enter from top or bottom — no mandatory orientation. Touch-protected terminals reduce the risk of accidental contact during wiring. IP20 rating applies once installed in a distribution board with conductors connected; the device itself is not rated for wet or dusty environments.","metaTitle":"Siemens 5SU1654-7KK20 SENTRON RCBO, 20 A, 300 mA, Type A, C-","metaDescription":"Siemens 5SU1654-7KK20 SENTRON RCBO, 2-pole 1P+N, 20 A rated, 300 mA residual, Type A, C-curve, 10 kA (EN 60898) / 20 kA (IEC 60947-2).
