Feed from either top or bottom — no preferred orientation. IP20 with conductors connected and distribution board installed, so it's for enclosed panels only, not washdown areas. Touch protection is built in. The 300 mA residual current trip level is deliberately high; it's for circuits where nuisance tripping on a 30 mA device would be a problem (e.g., industrial ovens, large pumps with long feeder cables). The C-curve magnetic trip (5–10x In) handles motor start surges without dropping out. The 1 kA surge withstand (8/20 μs) means it survives lightning-induced transients on the line side without damage.","metaTitle":"Siemens 5SU1654-1KK40 SENTRON RCBO, 40A, 300mA, C-Curve, 2-P","metaDescription":"Siemens 5SU1654-1KK40 SENTRON RCBO, 40A rated, 300mA AC residual current, C tripping characteristic, 10kA (EN 60898) / 15kA (IEC 60947-2), 2-pole, IP20, halogen-free.
