The 1P+N configuration means it switches the live conductor and monitors the neutral for earth leakage, while the neutral is not switched. The 32 A rating is the continuous current at 30 °C ambient; above that, the device derates linearly — 30.4 A at 40 °C, 28.8 A at 50 °C, and 24.64 A at 70 °C. Mounting position is unrestricted, and the supply can enter from either top or bottom, which simplifies wiring in tight enclosures. The product designation follows DIN EN 61346-2 and DIN EN 81346-2 letter code F. Maximum power dissipation is 11.4 W.","metaTitle":"Siemens 5SU1354-0LB32 RCBO, 32 A, B Curve, 10 kA, 2-Module","metaDescription":"Siemens SENTRON 5SU1354-0LB32 RCBO, 32 A rated, B tripping characteristic, 10 kA breaking capacity, 2-pole 1P+N, 2 width units.
